Here is a sample with next if. (Quick language tutorial for my 1 year old. Smiles) `use strict; while(<DATA>) { next if /^Bad/; print; } __DATA__ Good:Good morning Bad:Shut up Good:You're welcome Bad:No!` [download]	[reply] [d/l]

When continuing a discussion in a new top level thread, it it is polite to provide a link back to said thread. For one thing, it would have avoided confusion about why you put quotes inside the regex. -Blake	[reply]
Re: Use of next if... by VSarkiss (Monsignor) on Nov 13, 2001 at 01:43 UTC
The basic answer is "yes". Presumably this statement appears in a loop; Perl will exit the loop if `$_` matches the five characters you've specified (not three). Your pattern matches, in order beginning of line double quote capital E capital M capital P double quote end of line The parentheses following the `if` are not necessary. Another way to do this would be: `next if $_ eq '"EMP"'` HTH	[reply] [d/l] [select]

Its a regex. Don't quote anything in it unless you want to match the quotes. And if you know they're all three characters, no need for ^ or $ : `next if /EMP/;` [download]	[reply] [d/l]

Is this possible? gosh, perhaps if you tried it you'd find out? Maybe adding a semi-colon might help if you're in the middle of a block of code. I'd drop the quotes unless you want to match them (vaguely worded question...) cLive ;-)	[reply]
