The MODSLNK option controls exit link-editing. When a MODS statement does not specify a link-editing code, the setting of the MODSLNK option determines whether or not the exit should be link-edited along with other routines specified for the same sort/merge phase. If you specify MODSLNK=N, MFX will not link-edit exits defined on a MODS statement if the link-editing code on the MODS statement is omitted.
The delivered default (MODSLNK=T) instructs MFX to dynamically link-edit exits defined on a MODS statement if the link-editing code on the MODS statement is omitted.
Note: The IBM Data Facility Removable Media Manager (RMM) has some
applications which use a MODS statement without a link-editing option. In these cases,
link-editing is not desired.
