Jamie,
The correct syntax for what you are looknig for is
expr size("$s2")
note the double quotes.
cheers, Shahrokh.

Hi!
Has anyone successfully used the table functionality offered by [expr]? I can get simple table lookup to work as follows:
float x symbol y | | [expr $s2[$f1]]
But I can't get any of the table functions to work. For example, [expr size($s1)] gives the following console output:
error: expr: syntax error expr size($s1) ... couldn't create
I am using expr 0.4 with PD 0.37.1 on Linux.
Thanks,
Jamie
