We have added a new shortcut command: LO can be placed to the left of any displayed machine instruction. If that instruction references storage, the locations will be decoded and either one or two storage locations will be displayed.
WARNING! The decoding will be done with the current Retry Level register values. So this display will be useful, only when placed on instructions that are at or near the current Retry Level execution location. And even then, the results are NOT guaranteed accurate unless it is used on the instruction to which the Retry Level PSW currently points. So LO must be used with a great deal of caution.
The update that implements LO is named DBC-1810A.
