Oh that's pretty cool - I don't really like $str eq '' anyway.. i like a more concrete test like isnull(xxx) or something where you can look at it and right away you know what it's testing for.
If you remove [$some = "";] you'll see "not defined" instead of "defined".
I have the necessity to use this command:
cat file1 | grep $A | grep $B
where sometime A and, or, B are not set.
For example:
I set A=@
never defined or set B
The above command send a cat error.
Any idea?
Thanks.

Hi,
I have to check whether an argument say $ARGV is not null in an if operator. Please let me know the operator. It would be great if you write a psuedo code.
Thanks in advance

Hi all, I have a stupid question on NULL and zero(0).
In a script I've been working with, one of the lines is:
if &&
then
The problem I seem to have is when $Current_csm2 is null, this if block is not triggered, and I don't get why because I was under the impression that NULL!=0

Locale::Currency(3pm) Perl Programmers Reference Guide Locale::Currency(3pm)NAME
Locale::Currency - standard codes for currency identification
SYNOPSIS
use Locale::Currency;
$curr = code2currency('usd'); # $curr gets 'US Dollar'
$code = currency2code('Euro'); # $code gets 'eur'
@codes = all_currency_codes();
@names = all_currency_names();
DESCRIPTION
The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO
4217.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
three-letter codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying currencies. 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:
$curr = code2currency('usd','alpha');
$curr = code2currency('usd',LOCALE_CURR_ALPHA);
The codesets currently supported are:
alpha, LOCALE_CURR_ALPHA
This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.
Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
currency is involved) are omitted.
This is the default code set.
num, LOCALE_CURR_NUMERIC
This is the set of three-digit numeric codes from ISO 4217.
ROUTINES
code2currency ( CODE [,CODESET] )
currency2code ( NAME [,CODESET] )
currency_code2code ( CODE ,CODESET ,CODESET2 )
all_currency_codes ( [CODESET] )
all_currency_names ( [CODESET] )
Locale::Currency::rename_currency ( CODE ,NEW_NAME [,CODESET] )
Locale::Currency::add_currency ( CODE ,NAME [,CODESET] )
Locale::Currency::delete_currency ( CODE [,CODESET] )
Locale::Currency::add_currency_alias ( NAME ,NEW_NAME )

Locale::Currency::rename_currency_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Currency::add_currency_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Currency::delete_currency_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
