V. Questions about programs
******************************************************************
41. What are the Goodies Disks and where do I get them?
See Appendix 4 of Appendix H for more info.
******************************************************************
42. How do I get access to the HP Calculator BBS?
You can access the HP Calculator BBS via a modem (note that this is
a long distance call for most people):
(503)-750-4448 2400 baud, 8N1
(503)-750-3277 9600 baud, 8N1
For those people who have access to the Internet, you can also
access the BBS via telnet to hpcvbbs.cv.hp.com [15.255.72.16].
See Appendix H for more BBS sites.
******************************************************************
43. What are files that end with ".zip", ".Z" or ".z"?
Files that end with ".zip" are PKZIP archives, which originated in
the MSDOS world. One program that can extract the files in ".zip"
archives is the Info Zip "unzip" program. An MSDOS binary can be
found as:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/unz50p1.exe
Sources for the unzip program can be found as:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/unz50p1.zip
For binaries for other machines, see the file:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/README
Files that end with ".Z" have been compressed using the Unix
"compress" command. To uncompress these files, you must use the
"uncompress" command on Unix.
Files that end with ".z" have *probably* been compressed using the
new "gzip" compression command. To uncompress these files, you must
use either the "gunzip" or "gzip -d" command. These commands are
not a standard part of Unix, and so you'll probably have to get the
sources via anonymous ftp from prep.ai.mit.edu (as /pub/gnu/gzip*).
Again, versions are supposedly available for non-Unix platforms.
******************************************************************
44. What is a "ship" file?
In the past, programs for the HP 48 posted on comp.sources.hp48 were
posted in the "ship" format. This format made it easier for the
comp.sources.hp48 moderator to distribute programs, but makes it
difficult for users to extract and use these programs. Many people
still use ship.
To extract programs distributed in the "ship" format, you need the
following:
1. A copy of the "ship" program, compiled for your PC, Macintosh,
Amiga, Unix workstation, or whatever. The sources to "ship" can
be found at:
cbs.cis.com: /pub/hp48g/dos/unship.zip
This zip file also includes the dos executable.
Binaries for MSDOS machines, Amigas, and some Unix workstations
can be also be found on wuarchive.wustl.edu, in the directory
"/systems/hp/hp48/Posting/ship_executables".
2. A copy of the latest Info Zip "unzip" program, or a .ZIP
unarchiver that understands the new PKUNZIP V2.04g format. Note
that you *CANNOT* use old unzip programs, as old unzip programs
do not understand the new compression formats. An MSDOS binary
can be found as:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/unz50p1.exe
Sources for the unzip program can be found as:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/unz50p1.zip
For binaries for other machines, see the file:
wuarchive.wustl.edu:/systems/hp/hp48/Posting/README
Once you have a copy of the "ship" and "unzip" programs, you use
"ship" to convert the ship-encoded file into a .ZIP file, and you
use the "unzip" program to extract the HP 48 files from the .ZIP
file.
******************************************************************
45. What is \->ASC or ASC\->?
These functions were written by William Wickes to facilitate
transferring HP 48 binary objects in an ASCII format (useful when
transferring objects via electronic mail or bulletin boards). Some
HP 48 objects, like libraries, cannot normally be converted into
ASCII, unlike program objects, and these functions make it possible to
do so.
The \->ASC function converts the object in level 1 into an ASCII
string, which can then be uploaded to a computer for mailing.
The ASC\-> function converts the string object in level 1 back into an
object. A checksum is used to ensure that the decoding is correct.
******************************************************************
46. How can I get \->ASC and \->ASC?
A copy of these programs are given in Appendix A, near the end of this
file.
******************************************************************
47. How do I get rid of the HYDE library?
Getting rid of the HYDE library can be fun. Here's how to do it:
1. Go the HOME directory.
2. Press left-shift (orange) LIBRARY. The calculator is now
displaying a menu of libraries attached to the HOME directory.
3. Press the menu key that says "STRA". You are now accessing the
HYDE library.
4. Press the menu key that says "JEKY". You have now disabled the
HYDE library and restored the old (standard) set of messages.
5. Make sure that a pointer to the library is not on the stack. The
easiest way to do this is to clear the stack using CLR.
6. Detach the library using:
:0:998 DETACH
7. Purge the library using:
:0:998 PURGE
When you execute the PURGE, the screen will "jump" or "be messed
up" for a brief moment. Don't worry about it -- it doesn't
hurt.
******************************************************************
VI. Questions about programming and advanced user functions
******************************************************************
48. I've heard the names "RPL", "Saturn", "STAR", "Voyager", etc.. What
do they mean?
ASAP
This is a simple Saturn assembler, written in the Perl language.
Chip8, Chip48, Schip, Schip8
This is a machine-code program that was inspired by the chip8
video game interpreter for the RCA CDP1802 microprocessor
several years back. Chip8 allows you to write a simple
graphics-based video game for the HP 48SX. Among the games
written are "clones" of breakout, pacman, and pong, to name a
few (about half?).
Chip48, Schip and Schip8 are two different names for an enhanced
version of chip8 specifically designed for the HP 48SX. People
have written programs to assemble Schip assembly language into a
form directly usable by Schip on an HP 48. Schip interpreters are
available for both G and S series.
HYDE
This is the "HYDE" library, whose only purpose is to change the
error messages in the HP 48SX to make it "user unfriendly".
ML
Machine Language. This is usually used in reference to HP 48
assembly language programming.
MLDL
Machine Language Development Library. This is a library that
allows you to debug machine language programs with only an HP
48.
PDL
"Program Development Link". This is an MSDOS program, sold by
Hewlett-Packard, that allows you to write and develop HP 48SX
applications from your IBM PC clone. Programs are written on
your PC, transferred to the HP 48SX, and tested from your *PC*
(and *not* the HP 48SX).
NOTE: The GX version was not out in the May #63 Educalc Catalog,
but is probably coming soon...
RPL
RPL is the name of the language used to program the HP 48 and
HP-28 series calculators. RPL stands for "Reverse Polish Lisp".
It's interesting to note that an HP Journal article incorrectly
described RPL as "ROM-based Procedural Language".
SASS
SASS is a simple Saturn assembler, written in C/yacc (BSD Unix &
Bison). It uses Alonzo Gariepy's mnemonics.
Saturn
"Saturn" is the internal code name for the processor used in the
HP 48, HP-28 series, and many other calculators (just about all
HP calculators since the HP 18/28 series).
STAR
This is the "Saturn Macro Assembler" (how "STAR" comes from
this, I don't know), an assembler that mostly uses Alonzo
Gariepy's mnemonics. It's written in C and runs on many
different machines (PCs, Amigas, Unices, etc.). STAR is
available via anonymous ftp from ftp.ai.mit.edu in
"/pub/star-1.04.4.tar.Z". It's also available from various
bulletin boards (the HP handhelds forum on CompuServe also has a
copy). The latest version is "1.04.4".
SWING
SWING is a library program that displays a graphical tree
structure of the directory hierarchy in your HP 48SX, and allows
you to move from directory to directory using the arrow keys (it
is supposedly based upon an old PD VMS utility).
System RPL
This is the name for the custom "operating system/language" used
to program the CPU used in the HP 48 calculator. System RPL
is a superset of the normal user RPL commands; in addition to
the normal, user-accessible RPL commands, system RPL includes
many lower-level functions. System RPL is a language one step
higher than assembly language.
HP has released a system development toolkit (for the IBM PC)
containing a system RPL compiler, assembler, and loader,
complete with a couple hundred pages of documentation. This
toolkit, while copyrighted, is, for the most part, freely
copyable. If you can find a BBS or archive site that has it,
you can download all of the system RPL files and documentation.
The HP development toolkit only runs on the MS-DOS operating
system. Alex Ramos has written a portable system RPL compiler
which runs primarily on Unix systems, and can emulate most of the
features available on the HP kit. The program is called RPL#+ (in
an analogy to 'C++'). RPL#+ is available from Ramos's email
server: send a message to ra...@engr.latech.edu with a Subject
line that reads:
"send hp48/rpp199c.zip"
without the quotes, and a daemon program will reply.
The program currently runs fine on Sun/OS 4.x, but bugs have been
reported on other systems, including Linux (bugfixes welcome).
USRLIB
USRLIB is a program that takes the contents of an HP 48
directory and turns it into a library object. It currently runs
under MSDOS.
Voyager
Voyager is an "interactive disassembler" for IBM PC clones that
disassembles HP 48SX RPL and machine code. You download a copy
of the RAM *and* ROM in your HP 48SX to your PC, and run
Voyager. Using Voyager, you can then view the disassembled or
unthreaded code. Unfortunately (or fortunately), Voyager uses
the HP mnemonics, and not Alonzo Gariepy's mnemonics. Voyager
is available from the HP BBS (I think), via anonymous ftp from
the HP BBS (hpcvbbs.cv.hp.com [15.255.72.16]), and from various
bulletin boards (the HP handhelds forum in CompuServe also has a
copy). The latest version is "1.07".
******************************************************************
49. Why do SysRPL programs run faster than UserRPL programs?
SysRPL is the built in language, custom designed for the Saturn
processor used the HP48 family. UserRPL is a "subset" of SysRPL. The
main reason for the speed difference is the fact that UserRPL commands
have built in argument and error checking. In SysRPL, the programmer
is responsible for all error checking to avoid memory clears.
******************************************************************

BYTES and CRC are calculated by the HP 48 BYTES command on the library
object itself, not its name. The ID and bytes are in decimal; the CRC
is in hex.
The 41 Emulator Card's libraries are not proper RPL objects.
Their size and CRC cannot be computed by the BYTES command.
"GD7:FRANCE" means "in the FRANCE subdirectory on EduCALC Goodies Disk
#7". GD1 and GD3 had only one subdirectory each.
"HAY" means Hither And Yon. Files in the "HAY stack" can be found at
various ftp archive sites, such as seq.uncwil.edu, and at various
BBS's, such as HPCVBBS. HAY is a polite way of saying: "It's
everywhere, so I'm not going to help you find it." The obvious
analogy to the proverbial needle and haystack, however, is apt.

Notice to programmers: User Flags 1 through 32 are reserved for end
users' applications. Do not use them in libraries. User Flags 33
through 64 may be used by libraries, but there is no HP channel
through which they are officially allocated. Use them with caution and
only if necessary. (Cf. "HP 48 Insights" by Bill Wickes, page 176).
Note: EduCALC #'s are Stock Numbers; for further info call EduCALC at
(800) 677-7001 or (714) 582-2637, Mon-Fri 8am-5pm California Time.
Goodies Disks' stock numbers are #GD1A, #GD1B, #GD2A, #GD2B, etc,
where "GD" means Goodies Disk, "1" ("2", etc.) is the number of the
disk, and "A" means 5.25 inch, "B" means 3.5 inch.
HP #'s are HP part numbers, which EduCALC uses as their stock numbers.

51. What information is there on the internals of the HP 48?
The most important documents are part of the "System RPL" development
tools, a completely unsupported set of IBM PC tools created by HP
Corvallis (the creators of the HP 48). The tools, which run on
MSDOS machines only, contain documentation on:
* System RPL (which includes information on HP 48SX display
graphics, keyboard control, etc.).
* Saturn assembly language ("Saturn" is the name of the CPU in
the HP 48), including information on a Saturn assembler.
* A system RPL compiler.
* A Saturn object file linker.
The completely unsupported system RPL development tools and
documentation are available to customers free of charge to help them
in HP 48 application development, subject to certain legal terms,
which are given with the tools (they're too long and detailed to
give here).
You can get a copy in one of the following ways:
* Anonymous ftp to hpcvbbs.cv.hp.com [15.255.72.16].
* Get Goodies Disk #4. For info, see Appendix H.
******************************************************************
52. Are there any viruses for the HP48?
There are several, and most are French. In the United States, a
virus called the "Michigan virus" erupted a couple of years ago.
There is a program on Goodies Disk #8 that checks for the Michigan
Virus. Currently, viruses do not pose an appreciable threat on HP48's

53. How do I store fields of variable length string data in a compact,
rapidly accessible manner that does not require the overhead of
storing strings in lists?
See Appendix E, "Compact Data Storage", near the end of this file.
******************************************************************
54. What is "Vectored Enter", and how do I use it?
Note: This works on the SX, but I have no idea whether or not this
works on a G/GX. Use at your own risk :-). If you try it, let me
know one way or the other so I can say if it works or not here in the
FAQ!
From: bi...@hpcvra.CV.HP.COM (William C Wickes)
The HP 48SX manuals do not document a very powerful feature that we call
"Vectored ENTER," that allows you in effect to redefine or bypass the
command line parser and to have a shot at the stack etc. after the command
line has been executed.
Keys that execute an automatic ENTER perform a two-step process:
1. The command line is parsed and evaluated.
2. The key definition is executed.
When flags -62 and -63 are both set, the system extends this process as
follows:
1. The current path is searched for a global variable named *aENTER
(here "*a" is the Greek alpha character--character 140). If present,
the command line is entered as a string object and *aENTER is
executed. If absent, the command line is parsed and evaluated
normally.
2. The key definition is executed.
3. The current path is searched for a global variable named *bENTER
("*b" is Greek beta--character 223).
If present, then a string representing the key definition is put on the
stack, and *bENTER is executed. The string is the key definition
object's name if it is a command, XLIB name, global or local name, or
an empty string for other object types; its primary purpose is to implement
things like the TRACE mode on other calcs, where you can print a running
record of what you do.
A simple example of the use of *aENTER is to create a more convenient
binary calculator, where *aENTER slaps a "#" on the front of the command
line so you don't have to bother when entering numbers.
******************************************************************
55. What is "WSLOG"?
It is an undocumented feature which stands for "Warm Start LOG".
Type in WSLOG in caps, and calc will list the time and cause of the
last four warm starts. This feature helps HP tech to fix your baby,
in case it crashes.
0 - log cleared by <ON> <SPC> then <ON>
1 - low battery condition, auto deep sleep mode invoked to save battery
2 - hardware failed during IR (time out)
3 - run through address 0
4 - system time corrupt
5 - deep sleep mode wake up (alarm?)
6 - unused
7 - CMOS test word in ram was corrupted
8 - abnormality was detected about device config
9 - corrupt alarm list
A - unused
B - card module pulled
C - hardware reset
D - system RPL error handler not found in run stream
E - corrupt config table
F - system RAM card pulled
