I currently have code that stores random numbers in a bat file that is
later executed.  Each of the numbers drawn correspond to a specific
graphic file that is to be displayed.  Instead of relying upon a bat
file, I want to be able to randomly draw numbers, shell to dos, execute
the imager for the number of the file drawn.

TIA

   SwapVectors;
   Exec(filename: string; commandline: string);

Note that filename must contain the complete path of the file to be
executed.  Let's say you want to run WordPerfect and WP.EXE is located
in the directory C:\WP51.  You do not want to use any command line
options.  The Exec command would be: Exec('C:\WP51\WP.EXE', '');
