Hi everyone, I need to read certain portions of a text file as shown in the code below. I extract values from the hash arrays constructed from this portion. It would have been easy if the portion had been of fixed size (i.e say, from line 50 to line 100). As it turns out, the module size can be increased or decreased based on the user as he adds new cells . Is it possible to formulate an adaptive parser for such a case ..??? Please help
