Hey Gurus:
Im having a little trouble with some Perl I wrote. Here is a sanitized snippet.
sub checkdb
{
foreach $_ (@_)
{
..
... # snipped code where we munge around the db and get our
... # $variable
if ($variable < $threshold)
{
$command = '/usr/bin/blah';
$UPDATE = `$command << EOF
$variable is the value from DB.
$variable is less that $threshold
EOF`;
}
else
{
}
}
}
This sub goes thru a list, checks the elements of the list in a database for its value, then returns $variable, which is a integer. Then I run $command, which expects some string followed by a carriage return. We SHOULD end up with something like this in the $command log file.
"23 is the value from the DB. 23 is less than 25"
Instead I get
"23 is the value from the DB. 29 is less than 25"
Im stymied how the $variable got changed while inside of the ``. $variable IS a global variable, but that shouldnt be a problem, since it should get reassigned for ever iteration of foreach.... right? Or does the perl code continue to roll on, even before the ``'s get to return?
TIA!
