I tried this:
print index(" \t.,;?!", ''); It output 0 in my case. So last words on a line seems to work. I don't know if this changes with the perl version though. So given this, will it be necessary to change end_char to ' ' ? or perhaps change both start_char and end_char to a ' ' to maintain uniformity? Thanks, Dwaipayan.
