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

XmListReplaceItemsPos(library call)									       XmListReplaceItemsPos(library call)

NAME
XmListReplaceItemsPos -- A List function that replaces the specified elements in the list SYNOPSIS
#include <Xm/List.h> void XmListReplaceItemsPos( Widget widget, XmString *new_items, int item_count, int position); DESCRIPTION
XmListReplaceItemsPos replaces the specified number of items of the List with new items, starting at the specified position in the List. When the items are inserted into the list, they are compared with the current XmNselectedItems list. If any of the new items matches an item on the selected list, it appears selected. widget Specifies the ID of the List widget. new_items Specifies the replacement items. item_count Specifies the number of items in new_items and the number of items in the list to replace. This number must be nonnegative. position Specifies the position of the first item in the list to be replaced. A value of 1 indicates that the first item replaced is the first item in the list; a value of 2 indicates that it is the second item; and so on. Beginning with the item specified in position, item_count items in the list are replaced with the corresponding elements from new_items. That is, the item at position is replaced with the first element of new_items; the item after position is replaced with the second element of new_items; and so on, until item_count is reached. For a complete definition of List and its associated resources, see XmList(3). RELATED
