While goto may be harmful and all, I have a need to use it in this case and it makes logical sense for the program flow. I'm trying to avoid hackind it with a loop, but my goto statement isn't working. Here's a code sample:
ASK_DATABASE:
ask('databasetype','Database type?','mysql');
my $found = undef;
foreach $cur (@databases) {
if (getConf('databasetype') eq $cur) {
$found = 1;
last;
}
}
unless ($found) {
output "Sorry, invalid option\n\n";
goto ASK_DATABASE;
}
This runs fine as long as I enter a valid database type (as defined in @databases), but if I enter something invalid, instead of goto'ing back to the call to ask() again, I get this:
Can't find label ASK_DATABASE at Conf/NewConfiguration.cm line 49, <STDIN> line 7.
If anyone has a recomendation on how best to fix this, it would be great.
