Error Messages in ROBOTC Code • 5

Common Warning Messages

Warning messages are used to notify you about possible programming and logic errors in

your program. With warning messages, the compiler is able to x or ignore the issues so

they will not prevent your program from compiling or downloading to your robot.

A common occurrence of warning messages are empty, innite loops in your code. In the

example below, the an innite loop is created, with no code embedded within the loop to stop

it from repeating forever. This is considered a warning, rather than an error, because it is

valid code and can be intentionally used by a programmer.

The warning message will inform you that there was a possible programming error caused

by an innite loop: “*Warning*:Possible programming error. Innite loop (unconditional

branch to itself) detected.”

Error Messages in ROBOTC Code

If creating an innite loop was your intention, you do not need to correct this message. If it was not

intentional, you can:

1. Include code within the curly braces of the while loop, for it to repeat.

2. Change the condition of the while loop, so that it does not repeat forever.
