Status: Unverified
FACT(s) (Environment):
Progress 9.1x
FACT(s) (Environment):
Sun Solaris SPARC
SYMPTOM(s):
Using INPUT-OUTPUT THROUGH with a shell script
Subsequently runs an external .p which displays data using the DISPLAY statement
SYSTEM ERROR: Memory Violation (49)
CAUSE:
The DISPLAY statement in the external .p is causing the error 49 because after the program returns to the caller we are unable to get the handle of the previously forked process.
FIX:
Although the error 49 is a bug, this can easily be worked around (until the bug is fixed) by defining a NEW SHARED STREAM and using it for doing I/O to the subprocess.
