oh, didn't know all of this, where it's documented?
just [bang<--[list prepend $0foo]--[expr size("$s1")] did the trick
thanks and sorry for the misleading.
Here's the proper way to do it:
[symbol $0-foo] | [expr size("$s1")]
substitute anything that outputs the symbol (with the symbol selector) that you want -- [makefilename], etc.

Last option would be to try using [sprintf], [makefilename] or similar to create the array name, and send to [expr size($1)] . Maybe....
Prost! D.
