Since posting, I've played with a PPT file in HexEdit and been able to do a simple replacement of a piece of text in a slide successfully. No errors uopn re-opening the file in PPT. Next two steps is
1) Write a Perl script that makes the same change as I did manually in HexEdit
2) Install the PPT Charting utility (gotta find my Office CD, I know it's aroud here somewhere...) os I can re-try these steps with a chart.
Thanks for "binmode". I did some reading and am not clear on editing files in binmode. I expect I'll be using simple regex's =~ s/$placeholder/$new_value, but will placeholder be the ascii string I'm lookig for (ex: **punchard_dons_placeholder**), or the hex code, or the binary code of that string?
If I can get this working, I'll post the salient features for reference.
