| Sorry for not Tk question.
I found in some perl script this syntax
$abc'def = 1;
Please what is the ' character? Why to use ' in variable name?

$abc'def is the Perl4 way to do $abc::def where 'abc' is the package name and
'def' is the scalar variable name.

It's legal to use the single ' in a varible name.
It sure screws up my perl syntax highlighting though. :-)
