How i can debug my own *.itcl scripts?
Where i can find error messages?
Is there a user guide where i can find all functions and objects that i can use to write?

Thanx for any info.

only way to debug is printf (or puts or echo or whatever)...
and u won't get any echo if there is a parse error...
as for the itcl specific functions, browse the forum... not sure if there is a place with all of them... i guess not.
