Extracting Data from a File

Hi

I need to calculate the number of occurrences of a item in a number of files using Perl.
The item appears continually throughout the files but in each case I only want to calculate it in certain blocks of the file.
Example - Calculalte the number of occurrences of a 'pass' in a block of code which starts with 'Start' and end with 'Finish'.
It is not possible to say start at line 1 and count the number of occurrences of the item until you reach line 5 as the files are all different sizes and the block is located at different places in all the files.

I'm sure this is possible but I just can't seem to get my head around this Perl scripting

Any help would be great
OOP
