Hi, I am trying to write a graphical interface that also has a command line.
My problem is that when I try to set things up to run a Dos command, my
egavga driver won't run.
for graphics, i need to uses initgraph(GrDriver, grmode?)
for dos, I need to use the compiler directive
{$M 20000,0,0}
The problem is that when I include the above compiler directive my
graphics procedures report that egavga was not installed.
Any help would be greatly appreciated

You cannot {$M ?, 0, 0} and have them work. On the other hand, DOS needs some memory to run in, so you can't {$M ?, 0, 655360} and use Exec. The solution is to reserve some heap, but also leave some memory for DOS. Why don't you try something like {$M 20000, 32768, 65536} (note that some minumum heap space must be present, this helps insure successful Initgraph.)
