  Hallo Heng |

I'm a systemprogrammer of Academy of Science of EAST-Berlin and member of
this list since several days. But I have been dealing with Assembler-
programming in VM/CMS for a longer time. I'll try to answer your questions |

To get a value from a rexx-exec or to modify it, REXX has a EXECCOMM-Interface.
For beginners it's not easy to use it, that's why some times ago I wrote a
macro. If you want, I'll send you the macro. But the condition for using this
EXECCOMM-Interface is: Being in an REXX or EXEC2-Environment |
I think it would be easier to rewrite the exec (for instance instead SAY an
EXECIO), as to write tricky assembler-programs (may be I did not understand
your basic problem ?).

To read a stack from an assembler-program use the WAITRD-Function via SVC 202.
For more information ask your system-engineer (where to read the description).
Hope this helps a little |

P.s. We are not a full EARN-member yet, so our node is unknown to most of the
     world (but we hope to stay it in september). So please, any answers do
     n o t  send to me directly, but through the list |
