The !Compare application enables files to be compared and differences listed in a variety of formats quickly and easily.
It was originally written to provide an easy way to identify those subtle, simple changes made between program versions which then bite back!
It was changed from a command-line program to a Wimp application, and considerably enhanced in the process.
The comparison types are:
Byte - simple byte-by-byte comparison. The difference display is in Hex and Character formats.
Word - simple word-by-word comparison. The difference display is in Hex and Character formats.
Line - simple line-by-line comparison. The difference display is in Character format.
Block - line-by line comparison, but if a difference is found it attempts to find the next lines which are the same to re-synchronise the comparison. The difference display is in Character format, identifying blocks of different lines.
Basic - as for Block, but the difference display will de-tokenise Basic programs.
Code - as for Block, but the difference display will disassemble words.
It should be easy to add more comparison types if required.
The differences are written to a file which is displayed, and then may be printed, kept or deleted as required.
The characters which are different from one line to the next can be marked.
