OPCODE members to identify opcodes in assembler text
SMP/E uses information stored in an OPCODE definition default set to differentiate macro invocations from assembler operation codes. If you wish to change the default set, the SMPPARM DD statement is required when SMP/E processes JCLIN with assembly steps.
Licensed programs or user products that use special assemblers recognizing additional operation
codes must provide an OPCODE member identifying those codes, and the name of that OPCODE member must
be specified in the OPCODE operand. For more information about defining OPCODE members for JCLIN
processing, see the SMP/E OPCODE Member Control Statements
topic in z/OS SMP/E Reference.
