Mapping the Common Open, Close, EOV Work Area

The IECDSECT macro maps most of the main work area that is used by open, close, EOV, access methods, and related components of the system. The general format of this area is described in Figure 2.

The IECDSECT macro does not generate a DSECT statement. You should code a DSECT statement before calling IECDSECT. The format of the macro instruction is:

NO specifies that you do not want symbols for a 32-byte basic IOB generated in the work area. We recommend no.

YES specifies that you want symbols for a 32-byte basic IOB generated in the work area.
