There is no quick converter to convert your files to newer code. You will have to rewrite them.

I recall there being a sort of staged upgrade path. Basically, you'd hit old .m or .mws files with a chain of updating programs. Each of those came with the various Maple product releases, but which individually might handle only some of the stages to get current to its own version (depending on how old were your sheets' original version).

I'm talking about before Maple 7, as there really haven't been the same degree of incompatible language syntax changes since then. I mean changes like the ditto's becoming %, etc.

I hope that you only try it out on copies of your originals. Sorry, had to say it.

Look here, for the supposed MapleV -> Maple 6 (or 7?) updtsrc. The FTP links don't work, but there's still something at the end of the HTTP links. I checked the old FTP site, and while there's lots of old stuff there, the updtsrc progs seem gone now. It's not clear from the wording which version(s) it handles, ie. R5, or R4, or R3, etc. I would guess that it is for MapleV R5 to Maple6 conversion.

Which version of MapleV do you have? Can we suppose that you have MapleV R5 (or 5.1) and have already run the updtsrc.exe (or the updt3to4.exe for old R3 .m files) that came bundled with it on any older R4 material you had? If so, then the Maple6 updtsrc link above might be enough to get the most outstanding language changes handled.

If your material is from MapleV R4, and you don't have MapleV R5's updtsrc.exe, then it's not so clear whether the Maple6 updtsrc will be enough. You might need to apply MapleV R5 updtsrc first. I forget whether it needs a full, licensed and functional R5 installation to work. I see one such R5 updtsrc.exe here. I'd try the Maple6 one before resorting to using this first.

If your material is MapleV R3 then you may even more to do, in the update chain. See here, for a lovely view of the kind of language incompatibilities Maple versions used to bring.

Of course, we're talking about getting the old code to run, not to modernize it to use the latest and greatest bits of Maple. If you can apply the Maple6 updtsrc to material that functions ok in R5, then hopefully most of the biggest problems will be resolved. If there are still some problems then at that point I'd suggest uploading an example to this site, so that we could look in detail.

Oh, another memory lane view (cancel the frameset).

I didn't realize these update conversions existed. Thanks for the links
