comparing code versions

I have a large program that has gone through several hundred versions. now I have a unit that works more or less as desired, but I can't find which version of the code I used tro generate the HEX [ yes, I know, I should be more organized, but with hundreds of modifications, that gets difficult].

Is there any reasonable way to compare a HEX file against a BAS file to see what the difference is? Obviously I can compile the BAS file, now I would have two HEX files, Can they be reverse compiled into machine language, so I can then compare two files? Or is there some better way to figure out which of several hundred Bas files compiles to a given HEX file?

thanks for any and all comments, even if I am told I should find something better to do with my time!

Hi George,

Try that:

This won't help you now, but you can always add a couple of lines to your prog in future to write the .bas version to eram each time the program runs (not in a loop or you will kill the eram!!) All you have to do is before you compile a new version of the .bas file, edit the "Const Swvers = xx" line in your bas file to the current version number.

Then when the chip gets programmed you will be able to see the version of the bas file in the chip eram memory itself, so you can connect a programmer months later and see which version of .bas file you programmed it with. Wink

I'm sure there is an easier way but this works for me!

HI luciano:
That gives me a modify date for the HEX file, but how can I tell the program date of a chip? It would be neat if there were a way to program into EEPROM a date [optionally] at the same time the flash is prgorammed. Studio does allow dor programming of EEPROM, but I don't know how to prepare a HEX file to do that.

Good to hear from you,
George

Never saw that!
It's amazing what the eye does NOT see.
As always, thank you!
