Could one of the esteemed monks who delves into arcane behaviour please assist me.

I have a snippet of code:

print STDERR "$rec->[IMP_WG] $rec->[CSC_HAN]\n";
if ( defined( $rec->[IMP_WG] ) &&
     $rec->[IMP_WG] ne '' &&
     defined( $rec->[CSC_HAN] ) &&
     $rec->[CSC_HAN] eq '1' )
{
  print "$rec->[CLASSIF] $rec->[IMP_WG] $rec->[SRV_PLT]\n";
}

That produces (in part) the following output (greenfox you can look away now):

CSC.MIDRANGE.SERVER.SUPPORT 1
CSC.MIDRANGE.SERVER.SUPPORT 1
CSC.MIDRANGE.SERVER.SUPPORT 1
Use of uninitialized value at stats2 line 190.
CSC.NETWORK.ENG 1
Use of uninitialized value at stats2 line 190.
 0
CSC.MIDRANGE.SERVER.SUPPORT 1
Use of uninitialized value at stats2 line 190.
 0
CSC.NT.SERVER.SUPPORT 1
Use of uninitialized value at stats2 line 190.

Line 190 is the 'if' statement in the listed code.

The input data is the result of a split operation and it is possible that the indexes IMP_WG and CSC_HAN could contain undef values.

This is perl, version 5.005_03 built for sun4-solaris.

use strict; and -w are in use.

Any suggestions about what I am missing?
