I have a keyboard input program that runs one thing if one key is entered
and another if another key is entered.  There are about ten different
options.  That means I have ten different if statements.  I am using
recursion because after I get one input I do the program over again.

The only problem with this program is that I have to hold down the key for
about a second before anything is recognized.  Is there any way to speed
this up?  Possibly by using iteration instead of recursion.  Here is the
code.   Any suggestions are greatly appreciated.  I left out the program
names and variables not needed.  I use getch to catch the keystrokes.  I
tried using the bioskey but that didn't speed anything up.  I am using DJGPP
to compile this:

/*********start code********

{
if (getch() == x)
{run_program();
run_program();
exit(0);}
if (getch() == y)
run_program();
if (getch() == z)
run_program();
if (getch() == a)
run_program();
if (getch() == b)
run_program();
if (getch() == c)
run_program();
if (getch() == d)
run_program();
if (getch() == e)
{run_program();
if ((getch() == f || (getch() == g))
run_program();
if (getch() == h)
run_program();
if (getch() == i)
run_program();
}

****end code**********/

Thanks.

Tom
