If the objects addressed by pointers in the PLIST are control blocks containing pointers to areas the caller must create, Rexx is unsuited to the task. E.g. such parameters make the SMP/E API unsuitable to Rexx. In contrast, the ICSF API wisely uses only pointers in the PLIST which can be created by ADDRESS LINKMVS, the programmer using D2C(), etc.. >If you are calling a main program, REXX handles everything.
