I want to read a file from a point where a regular expression matches and keep on reading till i hit another regular expression; while reading this part of the file ( binary strings of known size; search the appropriate position, parsed through a fil, make a replacement);
Adding more to what I wrote earlier:
there are two input file: used in step 1) & 3) and second one at step 2
parsed the input file which basically gives me three variables;
out of three varibles two are regular expression and one integer,
I match the first regular expression then after two line i have hard coded expression then i match my second regular expression from this point onwards there are strings of binaries in multiple line and i need to count the bits to the value equal to third variable (integer) and replace with known character;
then i pick another line from input file and repeatt the same process;
In short here is what i have done (step 1 &3) and where i am stuck (step 2 ):
1)Open and read first line of inputfile1 which gives a string and eventually three variables
2) two are regular expression one integer; use them to rplace the binary with know character; i am stuck as to how i read and replace the binary with know character
3) repeat 2 with next line from input file
I have done 1) & 3).............missing the heart of the problem step 2)

I am completely new to Perl so plaese provide me the tips for efficient codind as well.........here is sample of the code has been written so far
well
first off if your going to post code please use code tags it helps the experts read the code a lot easier if you want this solved then use code tags, i have missed a few errors in the script because of no code tags, so please use code tags.
second:
this could be a problem
Expand|Select|Wrap|Line Numbers
while ($read_mss_operation <= $#arr_msff){
try
Expand|Select|Wrap|Line Numbers
while ($read_mss_operation <= $arr_msff){
i have to leave for about 1 hr so ill continue to look at the rest of the script.

Thank You,
Icecrack,
arr_msff is an array variable (@arr_msff). $#arr_msff is used to get the last index of the array. That is not the problem.

To search for a pattern and replace it with any other character, you may use substitution operator(s///).
