Re: Trying to get NULL with use strict; - How???

[Tanton Gibbs]

Oh, I see what you are trying to do now...sorry.

$i will always exist...it will range from 0..20.

Therefore, testing to see if $i exists will always be true (except when it is 0).

You want to test to see if $value[$i] is true, so instead of saying

if( $i )

say
if( $value[$i] ) {
....
}
else {
  last;
}

The last will exit the loop for you.

    Sorry, my mistake...you wanted
    if( $i != NULL )
    and I gave you
    if( !$i ) 
    when I should have given
    if( $i )

      This did not work! :(

      I just replied to Dadivd Wagner's note, with the entire code, which, BTW, is 
heavily domumented! :)

      Something I got into the habit of doing back in QB 4.5 days! :)

      Didn't know that perl did not support NULL! :( :(

      Anyway, any other suggetions would be greatly appreciated! :)

      thanks,

      Chris

I'm not sure what you want here, but there is no NULL in perl.You might mean undef or 
0, in which you can just sayif( !$i ) { ....}HTH,Tanton----- Original Message -----

The following code fails:                if ( $i != NULL ) {                       if 
($j < 10) {                        print DUMPFILE "     $j) ", "$value[$i]\n" ;        
            } else {                        print DUMPFILE "    $j) ", "$value[$i]\n" 
;                    }                }as I have:use strict;At the very top.But I need 
a way to check and see if the array is empty...(4 items, but can have 20)How would I 
do this???TIA!-- Chris Anderson-- To unsubscribe, e-mail:
