in reply to Trouble getting size of list returned from sub
Could adding an evaluation to the end of the sub something like;
sub gettinglist{ $ListItemReturnedCount++ if { Item retrieved }; return $ListItemReturnedCount; }
be a possible alternative? Ok, perhaps if you are debugging but not for production as a very unexpectedly short list would be returned to a calling routine somewhere. So, seeing as the sub is returning a list anyway. Could you not retrieve the number from some other place, for example from the sub/routine to where the list is called from?
