Re: Perl/TK: how to set defaults for the whole script?

... keep it in a variable ...

Not being quite as adventurous as choroba or kcott, I will often use a constant for something like this. The other alternative is a Readonly hash, but  Readonly imposes execution overhead that may be undesirable. The functional approach of stefbv is also nice.

use constant SCALE_DEFAULTS => qw(-width 10  -length 200  -etc 42);

my $s = $MW->Scale(SCALE_DEFAULTS, -override => 1, etc...);
