seems to describe the MVSVAR("SYMDEF",string)
call; string is first substituted by rexx ... which I guess would mean that
eg "testing" is replaced by the value of the symbol 'testing' which, if
not set, is of course "TESTING"... then the mvs symbols are replaced.
(I think. I've not done any of this for 20 years.)
