$ZNAME(variable,0)
This function is supposed to tell me that argument 1 is a valid variable name or not.
Doesn't work with an array variable, eg W $ZNAME("WLCOM(I)",0).
Not a question, just a whinge really.....

Got round it with $ZNAME($p(Variable,"("),0)
I guess there is a danger that someone else might be checking if WLCOM(I) in its full stringy form is a valid variable name. Arguably it should fail in the same way WLCOM/I/ should.
Instead of using the first piece with $PIECE(variable,"("), I recommend using $NAME(@variable,0). $NAME has the advantage that it will likely be updated in the event of any changes to introduce new variable syntax, while $PIECE(variable,"(") will remain stuck with the simple syntax. One advantage of $NAME(@varaible,0) is that $NAME will also check the syntax of all the subscripts. One disadvantage is that all subscripts must be defined.
