Use the following commands and functions via SVC 202.

ATTN     - p. 166 VM/SP CMS Macros and Functions, put information on the stack.
WAITRD   - p. 181 VM/SP CMS Macros and Functions, read info off the stack.
SENTRIES - p. 526 VM/SP CMS Commands, returns in R15 the number of elements
                        on the stack.  (Like QUEUED() in Rexx).
MAKEBUF  - p. 134 VM/SP CMS Commands, create a new stack buffer.  The buffer
                        number is returned in R15.
DROPBUF  - p. 344 VM/SP CMS Commands, drop a stack buffer created by MAKEBUF

Hope this helps point you in the right direction.

Merry Christmas,
