Hi monks, this script accepts two numbers and prints the range. When I allow a negative for the first number it works: 
#!/usr/bin/perl

while (<>) {
        print if m!(^-{0,1}\d*)\s+(\d*)!m;
        print "$_\n" for ($1 .. $2);
        }

But when I allow both to be negative it doesn't:

#!/usr/bin/perl

while (<>) {

        print if m!(^-{0,1}\d*)\s+(^-{0,1}\d*)!m;
        print "$_\n" for ($1 .. $2);
        }

Could a blessed monk point out my folly please? Thanks for all the replies to my previous question (esp. dws) and TIA for this one. Jono
