Problem:

When running a COBOL program compiled to .gnt or executable, the following error occurred on an AIX system, with Server Express running in 64-bit mode:

Symptom: error 114 in module "mFFH" when running a COBOL program compiled to .gnt or executable.

The error 114 occurred while running an end-user application program, but could be reproduced using nearly any COBOL program, including the demonstration program pi.cbl provided with Server Express, for example:

mkdir /tmp/test
cd $COBDIR/demo/debug
cp pi.cbl /tmp/test
cd /tmp/test
cob -x pi.cbl
./pi

Additionally, when attempting to debug using Animator, or using system debuggers such as "truss" and "dbx", failed because the debuggers themselves would not run.

Resolution:

This error is caused by the /proc file system not being mounted. The UNIX command df | grep /proc returns nothing under such circumstances. System debuggers such as "truss" and "dbx", as well as the COBOL debugger Animator, and COBOL executable programs in general, require the /proc file system to be mounted, in order to run successfully.

The solution is to modify the disk file /etc/filesystems, specifying "mount = true" for /proc, and then to reboot. The error 114 will disappear and the debuggers will work.
