Actually for Enterprise Cobol V3 and V4
Using the Optimizer on COBOL v3 and v4 executables is a 25 year jump forward in
hardware technology and access to over 600 new hardware instructions already on
your machines.
ABO -Architecture Exploitation 0 to 11 In One Step.

Programs
All Pre-V5 COBOL compiler releases generated only base ESA/390 level code
The Optimizer, like COBOL V5, generates code up to z13 ARCH(11)
