Software method for implementing dismissible instructions on a computer

DETAILED DESCRIPTION The present invention comprises a method for operating a digital computer in response to the occurrence of an exception.
The computer examines data stored at a predetermined computer location, and also examines the instruction code of the instruction causing the exception.
The computer determines whether the instruction causing the exception is dismissible, depending upon the data in question and said instruction code.
The computer assigns the next instruction that would have been executed in the absence of said exception to be the next instruction to be executed, if that instruction causing the exception was determined to be a dismissible instruction.
The predetermined computer location may be a computer register, including a computer register containing the memory address of the code of the instruction causing the exception.
The determining step may then include comparing the contents of that register to predetermined values.
