I am learning REXX and I read about calling subroutines in compiled languages, but I did not encounter any information on calling external subroutines written in REXX. Can anyone provide some explanations and a small example?
Apparently, I have been looking in the wrong manuals... Neither the REXX reference manual nor the REXX user guide gave clear information on it.
The only issue remaining is that I would like to pass the values of a stem from a main script to a subroutine. Maybe it is not done given the amount of data to pass and the limits of REXX (20 arguments)? Please advise.
