---------- Post updated at 04:56 PM ---------- Previous update was at 07:47 AM ----------

actually, sorry, i replied a bit prematurely . it still doesnt work ... im still getting success when I go over the value "9" on $changes, ill give an example. Although your suggestion does at least make the statement work up to the value 9, but not beyond ...

Code:
#!/usr/bin/perl -w

my $force = "0";
my $changes = "9";

if ((( $changes gt "5" ) && ( $force eq "1" )) || (( $changes gt "0" ) && ( $changes lt "6" ))) {
        print "success\n";
} else {
        print "failure\n";
}

Code:
# test.pl
failure
#

but now when i switch the value of $changes to "10", it for some reason returns true

Code:
#!/usr/bin/perl -w

my $force = "0";
my $changes = "10";

if ((( $changes gt "5" ) && ( $force eq "1" )) || (( $changes gt "0" ) && ( $changes lt "6" ))) {
        print "success\n";
} else {
        print "failure\n";
}

Code:
# test.pl
success
#

Could anybody explain to me whats going on here ?, its driving me crazy Smilie

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
