I've tried implementing this but it seems to make no difference. Incidentally, the file I am trying to run is a .bat file. I have tried using an .EXE file with this solution as well with no success. My whole program is:

{$M 8192,8192,655360}
program dcdocsl;
uses crt,dos;
var
        inps:string;

begin
      clrscr;
      writeln('Dcdocsl strip prog');
      writeln('Ensure you have moved dcdocsl.?? to SPOOL directory');
      writeln;
      write('What is the extension number of the dcdocsl file > ');
      readln(inps);
      swapvectors;
             exec ('c:\temp\go_docsl.bat',inps);
      swapvectors;
end.

Have you tried to just pass in :

exec('c:\temp\go_docsl.bat','');

It Works fine on my PC.

it seems that the program is quiting on you.  this is because there may not be enough memory.

to find out what is run use the doserror variable to find out what error you are getting.
if it uis a memory problem redure the maximum heap size, like this:

{$M 8192,4192,65536}

and try to use a exe file instaed of a bat file.  when u use a bat file you may run into more errors because the exec procedure.
