HELP Please! Shortcut key for POLOR Mode

[H@w|<]

hi anyone. i am using hp 49g calculator. i wanted to know the short cut key
for RETANGULAR to POLAR mode.

1) What is the short cut key for Rectangular mode to Polar mode or vise
versa?

2) I always have to keep changeing complex number to polar so does anyone
know where i can find the polar sing that looks similar to '<' or assign a
key for fast input.

Thank you in advance to whom ever is writing back.

I don't believe that there is one, but assign the following short
program to a key or store it as a global variable.

\<<
-16. DUP
IF
FS?
THEN
CF
ELSE
SF
END
\>>
Checksum: # E4C4h
Bytes: 40.5

The angle symbol is on ALPHA RightShift 3.

You may be interested in the following menus:

Hold down LeftShift while pressing MODE, and then press ANGLE.

LeftShift MTH, then VECTR. Also press NXT to see the next page.

RightShift CMPLX (over the 1 key). Also press NXT to see the next page.

LeftShift MTH, NXT, CMPLX. Also press NXT to see the next page.

Note that ABS and ARG are available as shifted keys (over the divide
key).

Also, get acquainted with the newsgroup archive at
http://groups.google.com/groups?q=comp.sys.hp48, which can be searched
from http://groups.google.com/advanced_group_search?group=comp.sys.hp48.

Sorry, that should be ALPHA RightShift 6.

By the way, you can get to the character browser at LeftShift CHARS
(over the N key). If you highlight the character that you're interested
in, the quick way to key it in (if any) is shown at the lower left of
the screen.

Better yet, install the Keyman program and then run it's program to
assign a user key for rectangular/polar switching. Works great.

This suggests that you don't have an HP48G series calc,
which had convenient display-mode toggles on the keyboard
for both "polar" [display mode] and "radians" [input/display mode]

RAD toggle:
\<< -17. DUP IF FS? THEN CF ELSE SF END \>>

POLAR toggle:

\<< -16. DUP IF FS? THEN CF ELSE SF END \>>

You can name these whatever you'd like (except RAD and POLAR,
which are already built-in command names for something else)
and then assign those quoted names to any keyboard locations,
if you like.

Alpha right-shift 6?

> or assign a key for fast input.

If you don't very often use the "infinity function"
above the "zero" key, you can make it the "angle sign" key instead,
by performing 128 CHR 102.2 ASN just once to set it up
(and also turn USER [keys] on).

ASMTs from Keyman offers a choice of useful key assignments,
including a toggler on leftshift-hold pi. It toggles DEG/RAD
if SPC is hit shortly, and the 3 coordinate systems if SPC is
longer pressed while the shift is still hold. The toggler is
more comprehensive but yet smaller than the above one.

I've certain problems with UPLOADS on hpcalc.org. But one
may get the latest Keyman from
ftp://ftp.math.fu-berlin.de/pub/usr/raut/HP49/keys/
In the latest version, K&SA longhold operates as a key
recorder, giving access to menu options from encapsulated
applications from outside. Based on this, ASMTs contains
an item that automatically starts the flag browser without
any further key press if MODE is pressed a bit longer :-)

PS. for John. There is also a new version of Filer1 on
ftp://ftp.math.fu-berlin.de/pub/usr/raut/HP49/tools/
with all features you were asking for some month ago.
