Opcodes of RM-COBOL 85



Does anyone know where to get a reference of the RM-COBOL 85 Opcodes?

I'm looking for something in the form of

Opcode name / encoding / semantic behavior

I intend to build an interpreter.
Would you mind providing me link?
I apologize in advance for any misspelling errors.

Thanks
