Here is a snippet that would also validate the return code aka result
/* Execute the 'ls -l' command and capture its output */
call bpxwunix 'ls -l', , out., err.
/* Check the return code from BPXWUNIX */
if result = 0 then do
/* If successful, display the captured standard output */
say 'Command executed successfully.'
say '--- Standard Output ---'
do i = 1 to out.0
say out.i
end
end else do
/* If there was an error, display the captured standard error */
say 'Command failed with return code:' result
say '--- Standard Error ---'
do i = 1 to err.0
say err.i
end
end
exit 0
Here is the documentation for it

Subject: [EXTERNAL] Re: Obtaining the Return Code from bpxwunix in a REXX
progrm,
Bpxwunix uses STDOUT and STDERR for the output and error processing. So, add
them to your CALL statement
call bpxwunix cmd,,,stdout.,stderr.
say "stdout output : "
do i=1 to stdout.0
say stdout.i
end
say "stderr output : "
do i=1 to stderr.0
say stderr.i
end
Thanks,

Subject: [EXTERNAL] Obtaining the Return Code from bpxwunix in a REXX progrm,
Hello -.Im not well versed in Rex -.I'm executing a Rexx program in z/os from
tso Option 6I can issue a call to call bpxwunix 'ls -l',,out..I do get some
unpredictable results, and most of the time I get the desired results-In
other-words the results of the call to bpxwunix for ls -la is not consistent .I
have modified the code to obtain the Return code from the call to bpxunit
-..Here is the current source:ADDRESS syscall- "chdir " cmdstrg call bpxwunix
'Su'
RC = $?
Say 'RC From bpxunix .......' $?
Say 'RC From bpxunix .......' RC
call bpxwunix 'ls -l',,out.
RC = $?
Say 'RC From bpxunix .......' $?
Say 'RC From bpxunix .......' RC ..The issue is the Say command always results
the value of $? not the specific return code -.How do I get the return code
from bpxunix call and display it properly in a Rexx program505165 -Thank
YouPaul D'Angelo.
