The exsits operation is not the problem. What the error message says is that $cacheHOA{$sum} contains a string, apparently a file name, and when you do $#{$cacheHOA{$sum}} you are trying to use that string as an arrayref. You have not given enough code to show us where you are setting$cacheHOA{$sum} to a string, removing the arrayref that, presumably, was in there.

Thanks wog,

Your response about the exists operation lead me to really look at where the array ref is installed. I changed the following line (where ever it occured):



$cacheHOA{$sum}=($name);
[download]



to 2 separate lines:



$cacheHOA{$sum}=();
push @{$cacheHOA{$sum}}, $name;
[download]



and now it works, obviously i thought i was (in the one line version) assigning an annon array with one member, which also obviously did not work (why not?).

In the two line version i explicitly assigned an empty list and then pushed the member in.

Thanks for letting me bounce this off of y'all! Sometimes all you need is to have someone look at what your doing and say "Dude, you fscked that right here!"(points and smacks your head...)
