Why do you believe that it is wrong? Leave it (correct) as is.

I just came across a DEQ macro call, and I had to change it to MF=L / MF=E because of SIIS issues. Now I recognized that the former coder (in 1985 ca.) coded a 4th sub-parameter SYSTEMS on the first parameter - which is allowed (and relevant) on ENQ, but not on DEQ - if I read the documentation correctly. Because DEQ shares the parameter handling with the ENQ macro, this sub-parameter is not flagged and causes different code generation for the option parameter of the SVC 48. Now my question: will this option simply be ignored by SVC 48 ? Can I omit the SYSTEMS sub parameter, or should I leave the macro call (wrong) as it is ? Did something go wrong in the past ? Kind regards Bernd
