Hmm, how about the following idea: allow a multiReturn assignment indirectly
with a new variant of
"PARSE" keyword statement, e.g. "PARSE ARRAY ..."?
This way, in ooRexx 5.0 one can return an array which than can be used to
assign its elements to
different variables. Something like:
/* assign elements of an array to variables */
PARSE ARRAY test() one two . four 1 st.1 st.2 . st.3 .
say "one: " one "two: " two "four:" four
say "st.1:" st.1 "st.2:" st.2 "st.4:" st.4
::routine test
return ("eins", "due", "troi", "four", "pet") -- multi return
This would yield:
one: eins two: due four: four
st.1: eins st.2: due st.4: four
I would suggest to intentionally keep this restricted to array objects, such
that no idiosyncracies
can occur. It is up to the programmer to create the appropriate array object
which is very easy
(e.g. using makearray, allindexes, allitems and the like). Absolute and
relative numbers could be
supported carrying forward those abilities from other PARSE keyword statements.
This array variant of PARSE would fit very well into the existing applications
of PARSE (I remember
to learn from Les Koehler how to initialize multiple variables in a single
statement using the PARSE
statement).
What do you think?
