I need to write some code to allow users to specify which of a whole
bunch of elements(e.g.512/1024) that they want to view. My idea for
how to do this was to have them input a semicolon delimited list, for
example:
1-10;25;33;100-250
i tried using this to check to make sure they input a valid list that
i can process:
[...]
$str =~ m/^((\d+-\d+|\d+);?)+$/g;
However, this does not consider 250-100 to be invalid.
