z/OS has program objects and load modules. Within legacy load modules there might be segments or overlays. But a/OS does not have phases.

While z/OS has the information for the original different CSECTs used to build the phase, z/VSE only saves the main CSECT identification information. Restated, all the subroutines that may have been hard-linked to the phase are in the phase, but there is not enough information to remove or replace one of the csects. So, when you punch the phase from z/VSE, you will see only one CSECT for the total program. In this discussion, the problem is that even if the COBOLII program was linked with LE 'parts' in z/VSE, those LE 'parts' may try to use z/VSE only pointers to branch into LE. So, I don't think it's going to work.
