GOAL:
How to get the exit code from a command line program?
GOAL:
How to retrieve the process exit status in the ABL?
FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
All Supported Operating Systems
FIX:
When using the INPUT THROUGH, OUTPUT THROUGH or OS-COMMAND statements, it is not possible to retrieve directly the exit code from the command in the ABL.
As a workaround, it is possible to enclose the command to run in a batch script which records the exit code and then prints it to the screen (for INPUT THROUGH) or save it to a file (for OUTPUT THROUGH or OS-COMMAND) which can be read later.
Retrieving the exit code on Windows
Create a .bat or .cmd script, which runs the command and then records the ERRORLEVEL variable.
Retrieving the exit code on Unix
Create a shell script, which runs the command and then records the special shell variable $?
