Disregard. This was a problem in the return value from get_value(), not the while loop test. Sorry to bother everyone.

Got this simple while loop:

sleep 60; my $status; while(!(($status = get_value()) eq 'initializing')) { sleep 10; }

The $status is set to the value returned by the get_value() function. When the value returned is no longer 'initializing', I want the loop to terminate. However, the while loop never terminates. It keeps going even when get_value() returns 'ok' and I'm not sure why. I've tried a few different iterations of this code to no avail.

This simplified version code works as expected:

use strict; use warnings; my $count = 0; my $status; while (($status = gv() eq 'initializing')) { print 'stuck in loop' . "\n"; } sub gv { $count ++; return 'initializing' if $count < 5; return 'ok'; }

But when I try to duplicated this in my real world code, it doesn't work.

$MCF = "Most Clueless Friar Abbot Bishop Pontiff Deacon Curate Priest Vicar";
$nysus = $PM . ' ' . $MCF;

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
