Both AZTEC (MANX) and BDS C support the 'exec' statement or an equivalent,
that allow a program to call another.  

NOTE:  These calls are NOT forks, so you cannot return to the original
program.

I believe both systems supply enough of the source to show how it is done.
(if I remember correctly, the file name of the new program is stored
in the BDOS buffer (?at BDOSBASE+8 (?)), and a couple of pointers need
to be set up pointing to the start and end of the filename.


If this is not enough help, send me mail, and I will try to look up
the details.
