Does anyone know of a program that converts between the different TPU
formats used in varying versions of Turbo Pascal ?
thanks

One way to do it is: 1. Read and decipher source .Tpu 2. Translate references to System.Tpu to target version offsets 3. Write target .Tpu in target version format. This should work for converting Tpu's as long as the versions use the same calling convensions. (There are some diffenrences between 4.x and (5.x,6.x) when passing extended reals). (I didn't say anything about this being easy!) For help on 1. & 3. see the different Tpu-file-listers out there. On 2.: For each version of the system unit, one might establish a correspondance between offsets and routine names. I think most of these pairs (offset,name) can be found when listing System.Tpu (correct?)

One problem here is what to do when converting a 5.5 TPU to a 6.0 if the unit contains any references to FREEPTR. The whole issue of heap management between these two versions would seem to present something of an enigma... -- Steve Gabrilowitz Martin Marietta, Orlando Fl. sag@iplmail.orl.mmc.com Fidonet 1:363/1701

In general, true, but I do have a piece of software that proports to convert 4.0 TPUs to .OBJ files, which could then be linked in to a 5 - 6 code. I haven't tried it, I don't know if it works or anything. If you (or anyone) are interested, please mail me, and I'll find out more.

Since this is a question that has been adressed to quite often, I take it that many users have the same problem, and would like to have a solution. If you, or anyone else, can find a reasonably safe working solution that is simple enough to use, let's make it publicly available. I understand from your, and an earlier posting that there might be the tools for a complicated multiphase conversion (although we don't know quite for sure?), but many users would like to see something easily manageable. Would this at all be possible? I am naturally offering garbo services for carrying out the distribution part of the load, if someone works out a solution. ...................................................................

Conversion is only necessary because the creators of TPUs distribute compiled code rather than source. I came to the conclusion soon after TPUs appeared in the Turbo Pascal series that the loss of control in becoming dependent on other people continuing to be there to upgrade compiled TPUs would outweigh any benefit to me. But I also understand the creators' wish to keep control.
