M204.0030 Model 204 needs 370 instruction set
Model 204 uses instructions which are not supported on the IBM System/360 (or equivalent) and requires the System/370 instruction set. Since Model 204 cannot proceed further, it will terminate with a return code of 4 in the initialization step.
System manager response: You cannot upgrade to a Model 204 release past Release 7.1 because of this restriction. Contact Technical Support for assistance.
