Intrinsic-76 TestC

76: boolean:= TestC;

When control-C trapping is on, TestC is used to determine if the control-C or control-Break keys were struck. If either one was then TestC returns "true".

Each time the control-C or control-Break key is struck, a status flag is set. When TestC is called, it returns the state of this status flag and then resets it to "false".
