Thanks, but that's not what I meant. What I meant was if one of the
return values was boolean, and one an int for example, and you wanted
to check the returned boolean without bothering to assign it to a
variable! I presume that this doesn't make sense to do (so probably
can't be done) - I'll have to check my Occam books toinight!

It probably wasn't worth mentioning in the first place :-)
