[PD] expr size() refuses some array names

[colet.patrice at free.fr]

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.
