IF and ELSEIF each test for TRUE. IFNOT and ELSEIFNOT each test for
FALSE.
Input register for 32-bit ports A.
Clear semaphore to false and get its previous state; TRUE or FALSE.
Check out new semaphore and get its ID; 0-7, or -1 if none were available.
Return semaphore back to semaphore pool, releasing it for future
LOCKNEW requests.
Set semaphore to true and get its previous state; TRUE or FALSE.

Return value variable for PUB/PRI methods.
Exit from PUB/PRI method with optional return Value.
Round floating-point constant to the nearest integer at compile-time, in any
block.
