Dear Sir,

Good morning/after noon. I need your valuable help, sir.

We migrated from Sco OpenServer 5.0 and Informix 7.20 to Sco Open
Server 6.0 and Informix 7.32. When we compile programs with Window
declaration, it can not execute but terminates the application. We
have checked the terminal type which is, at386-ie. When we made
changes to my .profile i.e.
eval `tset -m at386-ie:at386-ie -m vt100:vt100 -m ansi:${TERM:-ansi} -
m :\?${TERM:-ansi} -e -r -s -Q` the initial setting being:

eval `tset -m scoansi:${TERM:-scoansi} -m :\?${TERM:-scoansi} -r -s -
Q`

All these do not seem to bear expected results. Because we expect a
menu like this:
+---------------------------------------------------------------------
+
¦PPSystem: Payroll peRsonnel SDF Quit ¦
¦Select Payroll System Functions ¦
+---------------------------------------------------------------------
+
Which is not coming.

In the /etc, the ttytpe entry have the following entries:
at386-ie console
at386-ie syscon
at386-ie systty
at386-ie tty01
at386-ie tty02
at386-ie tty03
at386-ie tty04
at386-ie tty05
at386-ie tty06
at386-ie tty07
at386-ie tty08
at386-ie tty09
at386-ie tty10
at386-ie tty11
at386-ie tty12
unknown tty1a
unknown tty2a
dialup ttyp0
dialup ttyp1
dialup ttyp2
dialup ttyp3
dialup ttyp4
dialup ttyp5
dialup ttyp6
dialup ttyp7

The following program runs and executes:

DATABASE "/srs-prps/ppsys/phaseI/ppdb"
MAIN
DEFINE ans CHAR(1)
DEFINE pline INTEGER
DEFINE flag CHAR(1),
w_authorized SMALLINT,
w_userid LIKE userrec.userid
LET pline = 7
### OPTIONS PROMPT LINE pline
WHILE pline <> 10
### OPEN WINDOW wdw AT 4,6 WITH 7 ROWS, 60 COLUMNS
ATTRIBUTE (BORDER)
### DISPLAY "Rows = 7, PROMPT LINE is set to ", pline at 2,
6
### PROMPT "123456789012345678901234567890abcdef" FOR CHAR
ans
### CLOSE WINDOW wdw
LET pline = pline + 1
display " loop ", pline
### OPTIONS PROMPT LINE pline
END WHILE
LET w_userid = FGL_GETENV("LOGNAME")
SELECT TRUE
INTO w_authorized
FROM userrec
WHERE userid = w_userid
### DISPLAY "Rows = 7, PROMPT LINE is set to ", pline at 2, 6
display "Reached Here "
display pline
display w_userid
sleep 6
END MAIN

But when the comments are removed, it crushes and dumps. When we run
run on the server itself we got error -1135. We tried to run this :

case "$1" in
ansi)
# change console term type
defadm coterm TERM=ansi
sed -e 's/^at386-ie/ansi/' < /etc/ttytype > /etc/ttytype.$
$
cp /etc/ttytype.$$ /etc/ttytype
rm -f /etc/ttytype.$$

# change console font
defadm cofont COFONT=pc850

# remap function keys
[ -f /usr/lib/keyboard/strings.d/at386-ie ] || \
cp /usr/lib/keyboard/strings /usr/lib/keyboard/strings.d/
at386-ie
cp -f /usr/lib/keyboard/strings.d/ansi /usr/lib/keyboard/
strings
;;
esac

/sbin/loadfont
mapstr
But this did'nt seem to work. It came up with :

UX:pcfont: ERROR: pcfont can only be run from a virtual terminal
UX:pcfont: ERROR: on a graphics workstation
mapstr: cannot put key strings: Invalid argument

I renamed the termcap in "/etc/termcap" and "/u/informix/etc/termcap"
and copied these files from Sco Openserver 5. Since I am not quite
competent to handle these files, I did not want to take chances and
mess up.

When I compiled, using our terminal emulator, "EWAN", the program
exited and terminated the application. I went and logged on the server
and re-compiled and run the program and it displayed the following:

Program Stopped at "Wintest.4gl", line 24
which is:
DISPLAY "Rows = 7, PROMPT LINE is set to ", pline at 5, 3
error number -1135
The row or column number in DISPLAY AT exceeds the limits of your
terminal

What I noticed though, is that there was no core dump this time as was
the case previously.

Other than the termcap, we have the following settings:
Internal Codeset Console Codeset
ISO8859-1 IBM850

I wonder if the font type and size would be an issue. If I have to
make changes to the termcap, what are these changes ? I have looked at
the code, I can't easily work my way around.


What would be the correct console terminal settings for our version or
could it be something else ?


We need your help. Thanking you in advance.
