This is a limitation of the OS. On Unix and Linux, the largest return
code value that you can have is 255. Anything over 255 causes the return
code to be "rolled over".
You can see this by running a simple shell script on your Linux system:
> cat test.sh
#!/bin/sh
exit 4002
> ./test.sh
> echo $?
162

[staf-users] Return codes in Linux?
I have a curious problem, but I am not sure if it is me or STAF, I
defined three new return codes, 4001, 4002, 4003, but they are not
returned correctly to the shell (ksh):
# infares request resname tut
Error submitting request, RC: 7
Additional info
---------------
You must have at least 1, but no more than 1 of the option(s), RESTYPE
# echo $?
7
- this one comes back OK, perhaps because it is a low value? But:
# infares request restype % resname tut
Error submitting request, RC: 4002
Additional info
---------------
No free resources found
# echo $?
162
It looks like the shell only accepts 1 byte return codes? But ksh is
used universally - surely it would have been caught already?
