72A-10: When ATTACH is invoked in AR-ASC mode: Non-zero ALETin AR15. When ATTACH is invoked in primary or AR ASC mode: non-zero ALET in parameter list
>I do not see tokens involved with ATTACHX. >Can someone please explain what IBM is talking about? IBM is talking about what the book says: access list entry tokens (ALETs). It might help to show the expansion of the macro, and possibly the assembly listing for that section. If you coded exactly what you showed, your expansion would have included LAE 15,IHB0001 And that in turn would put a value in AR15 that depends on what your ASC mode was and what base reg this resolved to, according to the architecture of the LAE instruction. If you were not intentionally in AR-ASC mode, or if your AR15 would have been 0 when the SVC 42 was issued, then you likely have an overlay of your program such that the assembled parameter list no longer contains 0's in all of the slots reserved for ALETs of parameters.
