Need Help??

This should do it:

if ( $DataEntry =~ /^\d+$/ ) { 
    print "good entry";
} else { 
    print "bad entry";
}

Add in a test for zero -- that passes through this regex, but is not a positive integer by any definition I'm aware of.	[reply]

That also passes for `"123\n"` which could be good or bad. Use `\z` instead of `$` if you don't want to allow a trailing `\n`.	[reply] [d/l] [select]
