Alternate modifier keyword procedure

Use this procedure if the previous procedure has not isolated the failing media manager function, or if the type-of-failure is other than abend, wait, or loop.

Function keywords divide the media manager into logical areas. A unique acronym identifies each of these functions.

1. From the following list, select the modifier (function) keyword that describes the area you suspect of failure.

   Function	Description
   CNVT	Converts relative byte addresses to absolute device addresses (CCHHR), and vice versa. The CNVT function uses modules ICYCCHHR and ICYRBA.
   FMTWR	Processes requests to format and write tracks sequentially. The FMTWR function uses modules ICYABN, ICYABN, ICYBLDCP, ICYBLIST, ICYDIE, ICYFW, ICYNRM, ICYPGAD, ICYRBA, and ICYSTOR.
   INIT	Initializes the media manager control blocks. The INIT function uses modules ICYIEDB, ICYILPMB, and ICYINIT.
   MMSYSTEM	Manages media manager resources. The MMSYSTEM function uses modules ICYELE, ICYFRR, and ICYPURG.
   PFMT	Processes requests to preformat tracks within a range of relative byte addresses. The PFMT function uses modules ICYCCHHR, ICYPFCP, ICYPFMT, ICYRBA, ICYSTOR, ICYPFDIE, and ICYPFAPP.
   RDWR	Processes requests to read or write the data portion of records. The RDWR function uses modules ICYABN, ICYBLDCP, ICYBLIST, ICYDIE, ICYNRM, ICYPGAD, ICYRBA, ICYRDWR, ICYSORT, and ICYSTOR.
   SRV	Set of functions that interface with a catalog to obtain data set information and to update that information when explicitly requested. The SRV function uses modules ICYMMSRV and ICYMSTAE.

2. Specify the modifier keyword as FMTWR.
