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. </Black team mode> >OTOH, there is no documented interface for a REXX variable pool not created by >REXX. > IRXEXCOM can set Rexx variables.
