Two questions / observations regarding rexxref.pdf:
5.3.2. The Collection Class
5.3.2.16. union
...
>>-union(argument)-<
The argument must also allow all of the index values in the receiver collection.
>>> add: The ITEMS in the argument must be acceptable by the receiver
>>> collection.
5.3.15. The Stem Class
5.3.15.4. []=
>>> add: the index used for the stem object is the required string value of the
specified index object.
My test
pa=.payroll~new(1,'Walter',1000) -- an object
M=.Stem~new; m[pa]='I' -- string value of pa is used as index
correct?
Regards
Walter
