Xvfb - yes, normally a good idea, but it was included in the "etc."

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.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
