I wrote an expr with If-arguments in it to range values. First I tried it with 5 lines of If-arguments an everything worked fine. Than I tried to get more If-arguments into the expr to get better results BUT after 9 if-arguments everything crashes: Pd closes immediatly and when I reopen and try to change something in the expr Pd crasches again. Even if I try to erase lines out of the expr -> CRASH...

I get the same problems as well as other interesting error messages :

error: expr: ex_eval: unexpected type 0 expr: bang: unrecognized result 1931591688

Are the Objects limited to a specific number of signs/rows/arguments? Any ideas?

[expr] may have its own limitations that no-one really knows about.

I wrote a replacement for [expr] named [#expr] :

http://gridflow.ca/help/%23expr-help.html

I wrote it because I wanted to expand [expr]'s feature set to work on grid data but currently [#expr] is just a replacement for [expr] with a few more features and a few missing features.

get it at http://gridflow.ca/

make sure you get version 9.13 which fixes bugs in [#expr].

There's no expression size limit in [#expr].

There is no replacement for [expr~] nor [fexpr~].

[#expr] doesn't allow writing a trailing semicolon.

You don't need semicolons in your expression if you are just going to add the results together : just replace them by plus-signs.
