Alternate Entry Name: .OFLOW
B: status = overfl([type]);
C: int overfl( [int type] );
OVERFL executes one of the "transfer on overflow" instructions ("tov", "teo", or "teu") to check one of the overflow bits in the indicator register. This will determine if the bit is on or off. Executing any of these instructions will turn off the bit if it was on.
B programs start with the overflow faults masked, so that overflows do not cause faults.
