Monks,

I am new to the concept of tie-ing and would like to know if it is the solution to my problem.

The previous authors used a hash to store a customer file, using a pin as the key, and separating the needed fields by pipes as the value, e.g., $hash{$pin} = "$field1|$field2|...";. During the processing of another file, the values are repeatedly re-split to get the information.

My approach was to use a hash in place of the pipes, e.g., $hash{$pin} = { field1 => $field1_value, ... };. This results in "Out of memory!"--The file is ~2.5gig.

The file is fixed length and it is used repeatedly; therefore, re-parsed and re-split repeatedly. Should I parse it into the format I need when it first comes in and then use tie within the code? I've been reading up on tie and it seems very neat. Is it able to work just as quickly with such a bulky file?

Thanks for your guidance.
