[MacPerl-Forum] Scope problem ? "my" variable %in masks earlier declaration in same scope.

[Jimmy Lantz <webmaster@ostas.lu.se>]

Hi, I have a script where I get this problem,
I haven't changed anything all of a sudden the syntax check complains on this.
Does anyone have any ideas on why this occurs?
All help appreciated.
