in thread Associating filehandles with Perl::Tk widgets?
Okay, that's awesome! I used the first option, and that takes care of a couple of my problems! It's really nice, because I don't have to worry about newlines, either. The only thing is I get the following warning: Use of uninitialized value in formline at ./sl-brad.pl line 375. Here's my code:
sub swrite { croak "Usage: swrite PICTURE ARGS" unless @_; my $format = shift; $^A = ""; formline( $format, @_ ); return $^A; } #end sub swrite()
I know it's just a warning, but I'm looking for clean code. I assume it's not liking the @_ in the formline statement. Perhaps I should just assign it to another variable?
