dear win32 perl users, ive never actually known how to 'modfiy' a file using perl on win32. up till now, ive always read file1, found the data i intended to change, and have always created a new file 2 containing the changes. if i wanted to 'simulate' changing file1, when done i could rename file2 to file1. in other words, ive never learned how to modify a file directly.
ive read win32 makes it more difficult to do this than on unix os's. but in any case, today i wanted to ask the group. assumming 'file1' exists with the following 3 records in it: A B C is there a 'simple' code fragment someone could post that would demonstrate iterating through this file and when record 'B' is encountered, we want to change 'B' to 'B_modified' - done in a way where we only access 'file1'. maybe this cant be done, but im asking. yes i do realize there is another approach, upserp contents of 'file1' modify in memory, delete 'file1', then recreate it by dumping the in-memory modified contents. this seems more like a 'hack' than a direct manipulation of the original file. anyways, thanks to any who might be willing to enlighten me about this topic. greg
