sometimes I'll get an error - 16 bit MS-DOS Subsystem.
Sounds like the "ComSpec" environment variable is somehow
being changed from the CMD.EXE default to scuzzy old 16 bit COMMAND.COM
(or similar 16 bit shell), which if changed by the script, will cause
the script to then be unable to invoke any 32bit apps correctly
(eg. using system(), backticks, open(), etc)
If I run other example scripts, or other ones I've customised I don't
get any problems, so it must be something to do with this one script.
Make sure it's not a user specific environment problem first;
open a DOS window via "Start | Run | cmd.exe", and check
the value of ComSpec:
C:\>set | findstr ComSpec
ComSpec=C:\WINNT\system32\cmd.exe
^^^^^^^^^^^^^^^^^^^^^^^^^
C:\>
If that's set to something other than CMD.EXE, that's bad
and needs to be fixed.
If you find that setting to be correct, but invoking the script
from this DOS shell still fails, eg:
C:\>perl //path/to/your/submit-script.pl
..then I'd say the script is probably somehow changing ComSpec
(or #include'ing, require'ing or eval'ing a file that does this)
then fails when the script tries to later invoke system(), open(),
or `backticks`.
If you're still having trouble, send me a copy of the script
in private email, and I can possibly tell you what the cause is,
if indeed it is a problem just with this script, and not the others.
My guess is that some sequence of events in the script leads to
that variable getting changed, causing errors when it tries to run
other perl scripts.
I've trawled the internet, but can't
find anything that helps.
groups.google.com might be a better resource in this case
for the NTVDM error, not sure.
