Ahh, well I just did it in a *.input file, using the interactive
language rather than SPAD. Maybe you need to give the output type of
myFn, as in
myFn(inp:Boolean):Boolean==
outputList(["abc",1])@Void
inp
But I really don't know, as whenever I try and write in SPAD I always
get errors. So I'm just guessing here.
Hi Alasdair,
No I still get the same errors, even when I add the return type as below.
The error message seems to suggest it is failing to match on inputs
rather than outputs (although I don't fully trust the error messages so
its worth trying all ideas).
I do seem to remember Waldek saying, in an old email, that there is some
issue with matching on type 'Any' but its hard to search and find old
posts (there must be a better way of recording these issues). If that is
the issue it would be good to have a fix because I would have thought
outputList would be useful for others in addition to myself.
Thanks for the ideas.
Martin
