Imagine that a black box, possibly Rexx, possibly a host command
interface has set unknown members of compound symbol X. in
unknown ways. It might have done:
X. = 'Blanket'
X.PI = 3.14
Empty = ''
X.Empty = 'Vacuum'
drop X.WEIRD
Can a program knowing none of this except that unknown members of X.
have been manipulated discover with IRXEXCOM that:
There is a tail, 'PI' such that X.PI has value 3.14
There is a tail, null-string, such that the corresponding value of X. is
'Vacuum'
There is a tail, 'WEIRD', such that the corresponding value of X. is
undefined
For any other tail, the corresponding value of X. is 'Blanket'.
A similar question applies to STEMPUSH/STEMPULL.

IRXEXCOM can set Rexx variables. Can't it create new ones simply by setting
them:
