DLSuperC is an exceptional compare program!
Edit by : DLSuperC is an exceptional compare program. It features speed, accuracy (doesnt get lost) and versatility. It handles file sizes greater than 64K lines even in its older 16 bit Windows 3.x version - DLSuperC16. Importantly, DLSuperC allows a user to filter out or ignore changes that are temporarily considered as unimportant (e.g., programming language comments, reformatted lines and text upper/lower case changes). It, also, detects lines that have moved out of sequence (i.e., relocated code). It even compares two files that are composed of two unordered lists. This last compare is unique in that the order of the lines in the list is unimportant - just that the lines match, are absent, or are duplicates. you can free download DLSuperC 7.3a now.
