9.18 Special conditional expressions
-------------------------------------
C-- supports eight special conditional expressions:
CARRYFLAG
NOTCARRYFLAG
OVERFLOW
NOTOVERFLOW
ZEROFLAG
NOTZEROFLAG
MINUSFLAG
PLUSFLAG
These can be used in place of any normal conditional expressions. For
example, to execute a block of code only if the carryflag is installed, use
the following command:
IF( CARRYFLAG )
{
// here one or more statements
}
In order to keep executing a block of code until the overflow flag is
set, use the following sort of code:
do {
// here one or more statements
} while( NOTOVERFLOW );
