The OP had an incorrect starting assumption that "the system" knows anything at all about SDWAMODN. It does not. That is a field filled in by the recovery routine. The trio of fields SDWAMODN, SDWACSCT, SDWAREXN (often accessed as a group by the containing name of SDWARECP) contain whatever a recovery routine chose to place into them.
In the stated example, the system wouldn't know about "PGM2" at all. It wouldn't necessarily know about "PGM1" either, unless that was the name used for such a service as ATTACH, LINK, or XCTL. If the abending program is running in problem state under a PRB or IRB then there is a possibility that RTM2EPA will be set. For a PRB, it will be set to the value from CDENTPT if the RB has an associated CDE (RBCDE1). For an IRB, it will be set to the value from RBEP. For both of these cases there might be a module name. That is placed into SDWANAME. For a PRB, it comes from CDNAME (if there is a CDE). For an IRB, it comes from whatever CSVQUERY comes up with, based on the RBEP value. If SDWAEPA contains the EPA of PGM1, the odds are good that SDWANAME contains PGM1.
