Hi, I'm having trouble with using really long commands with spawn. Here's
an example:
strCommand = '"c:\program files\spectral\spec.exe" ' + $
string(x) + ' ' + string(y) + ' "' + strOutput + '"'
where x = 25, y = 25 for example
Now call Spawn, strCommand:
Case 1:
-------
for strOutput = '.\OUT\output.dat', everything works fine.
Case 2:
-------
for strOutput =
'c:\program files\spectral\develop\debug exe\output\first\output.dat', I
get
this error message:
% XMANAGER: Caught unexpected error from client application. Message
follows...
% SPAWN: Error executing spawn command.
A device attached to the system is not functioning.
There appears to be no problem with SPAWN in case 1, and after I quit case
2, I can still call SPAWN without any complaints. I suspect it's because
the command string strCommand is too long, since for shorter strOutput it
works, however after reading the help for SPAWN, I did not find anything
about a limit on the string length of command. Are there any workarounds
to this problem?
Thanks,
Will
