MAPDNTRY (Map Directory Entry) Macro
The MAPDNTRY macro generates a mapping DSECT, which can be used to interpret the information that is returned by the LOAD or FETCH macro, if DE=VSE or DE=YES is specified.
Format
Requirements for the caller
- RMODE:
- ANY
Parameters
- DE=VSE | YES
- DE=VSE specifies the directory entry that is returned, if DE=VSE was
specified in the LOAD or FETCH macro. For the layout and a description
of the DSECT fields, see Table 1.
DE=YES specifies the directory entry that is returned, if DE=YES was specified in the LOAD or FETCH macro. Table 2 describes the mapping and contents of the DSECT fields.
