Hi, I was wonderng if there is any way to load and run a TP program from within another TP program. What I'm looking for is a command similar to the CHAIN or LOAD"Prgname",R commands of basic. Any help will be appreciated. Thanks in advance, Paul "Dex" Durden Dex@cup.portal.com

In Turbo Pascal 3.0 it is possible for one TP program to execute another
using the "execute" command. It worked like this:
assign(fp, 'myorog.com'); { var fp : file }
execute(fp);
However, this only worked for TP .com files. In TP4.0/5.0, the "exec"
command is much more useful. You simply do "exec(path, commandline)".
The command line is optional, and non-turbo programs can be called.

Without a $M directive or a change to the high heap limit memory size compile option, there won't be enough memory for the program to run. The default is for a Turbo program to assign all free memory to the heap. I believe I've read that Turbopower's Turbo Professional library contains routines to dynamically free up memory for exec to use, but I don't know the details. Duncan Murdoch
