Hi, Well, of course, as soon as I posted I then spotted that I had not corrected quoted the stderr. stem varname.
Actually, the sample code did not come from IBM but from:- https://www.ibm.com/developerworks/community/blogs/MartinPacker/entry/bpxwunix_z_os_best_kept_secret10?lang=en A very good blog update from Mr Packer. The code below does work. My tests prior to quoting the stem variables did fail. Tracing did show they were being set to blanks. It took a little while longer to interpret and understand the trace. IBM examples are do not quote the stem variables, and are relying on the default STEM variable behaviour:- To trap output from the ls command and display it: call bpxwunix ’ls -l’,,out. do i=1 to out.0 say out.i end To send output from the previous example to word count and print the byte count: call bpxwunix ’wc’,out.,bc. parse var bc.1 . . count say ’byte count is’ count To trap output on stack and feed it to word count: if bpxwunix(’ls -l’,,stack)=0 then call bpxwunix ’wc’,stack ref: Using REXX and z/OS UNIX System Services SA23-2283-30 The post was to put in archives to remind that using quoted stem vars are better when calling bpxwunix.
