Run your Mathcad 5. Then under the "Help" menu choose "Developer's reference". In there, read the information on "Accessing Mathcad from within another application".

On the old Mathsoft - Mathcad website I found this, regarding Mathcad 6 (Mathcad 5 and 6 both supported DDE):

"First, follow the directions in the Mathcad User's Guide in the Appendix on DDE, and write a macro that sends the values of certain cells to particular Mathcad variables. "

Apparently in the user's guide for Mathcad 6 there is an appendix that deals with DDE. Unfortunately I have no access to my physical copy of that manual presently, and an electronic copy (.pdf) does not exist..

I did find there is a DDESERV.EXE in the Mathcad 6 directory. I tried running it, but it immediately complained about several missing .DLL files (file names all starting with an underscore). I did not see that DDESERV.EXE in the Mathcad 5 directory though...

I seem to remember that DDE is a mechanism where a client can ask a host 'what tricks it has in store'. If you can find a DDE description for another program, maybe it will explain how to do that and you could try it on your Mathcad 5.

 

Success!
