Yes, all the lines coded after the OPSYN will treat the "LA" instruction as a "LAY" until you suspend it with a new "LA OPSYN ,"
Mustn't one be careful with this sort of OPSYN because some library macros branch around generated code using absolute displacements rather than generated labels? If the OPSYNed instruction has a different length this will cause a wild branch.

I've never used OPSYN. Can this technique be used with the execute form of the CALL macro, so that the linkage items can be further away from the base registers.
