One option is to add the following two lines two your source.
! RE-STORE “C:\PATH\MYPROG” ! Save prog version
! RE-SAVE “C:\PATH\MYPROG.txt” ! Save ASCII text version
Then when you make a modification to your code you can also highlight and execute the re-save line. Then in git you can track the changes that happen in the ascii version when you check it into the repository.
