Example:
#DEFINE_CONSTANT DEBUG 1
DIGITAL_OUTPUT OUT$;
INTEGER I;
FOR(I=0 to 20)
{
#IF_DEFINED DEBUG
PRINT(“Loop index I = %d\n”, I);
#ENDIF
OUT$ = ITOA(I);
}
The value of the loop is printed only if the DEBUG constant is defined. In order to
prevent compilation of the code, delete the line that defines the constant or comment
it out.
