I thought I would try out using "bpxwunix" in REXX. The sample code worked fine.
But, I normally code with SIGNAL NOVALUE active.
Then the sample did not work. It took me a little while to work out.
This does work:-
/*REXX****************************************************************/
Trace 'o'
Signal on Syntax /* for unexpected results. */
/*===================================================================*/
unsorted_data. =
unsorted_data.0=5
unsorted_data.1="KIJJ"
unsorted_data.2="KQWR"
unsorted_data.3="ADGF"
unsorted_data.4="OEPE"
unsorted_data.5="VNVV"
sorted_data. =
sorted_data.0=0
cmd="sort"
call bpxwunix cmd,"unsorted_data.","sorted_data.",stderr.
say "sorted_data:"
say "======="
do i=1 to sorted_data.0
say sorted_data.i
end
say "stderr:"
say "======="
do i=1 to stderr.0
say stderr.i
end
Return
/*===================================================================*/
I have not listed the diagnostic section for the SIGNAL processes.
Note the quoted stem names. This is required.
