There is no question?
#define TRUE 1 looks a little obsolete, that''s one thing.

You might get help faster if you tell us what the problem is, or what it's supposed to do.

Now perchance would you now how to set all the values in a string to NULL, so that I would be able to write separate commands (say, GOLFT for the robot to go left, and then another command entirely, say GOFWD, in the same string?) The program will eventually be used to input sets of four numbers (aspects of a robot that I hope to build that will detect light and objects) and using them to determine waht my robot will do.
Basically, If you will, the program will be a testing ground for the intelligence of my bots.

Once again, thank you.

memset(RobotString, 0, SizeOfString);
or
bzero(RobotString, SizeOfString);

Depending on how many commands you have you could just have a byte/char stand
for one command instead of having to parse words in a string. If you needed
more commands then a byte could represent you use more then one for each
command.

FOWARD = 0
LEFT = 1
RIGHT = 2
BACK = 3

There was a old mac game called chipwits that was like your project.
There is a playstation game called carnage heart also. Both would probably
be good practice for programming robots.
