passed in R0 then that problem is solved by calling

I have some Rexx functions written in Cobol. Basically we receive the register
R0 as a first parameter in Linkage Section. So... Works like a function written

Sorry... My previous email I have made a mistake..

A recent thread on REXX raises the question of what compilers support
interfaces that require passing an address in R0 in addition to the PLIST
address in R1. A secondary issue is how to handle multiple callbacks from a
non-LE program without the overhead of establishing the LE environment each
