Operation code is not valid; specification is ignored.
30
Cause . . . . . : The Operation code is not valid. No further checking is done on the specification. The operation must start with a valid Operation Code and can be followed by an optional Operation Extender. If specified the Operation Extender must be one or more of A, D, E, H, M, N, P, R, T, or Z, and enclosed within parentheses.
Recovery . . . : Specify a valid operation, or omit the specification. Compile again.
