MAPDEL
MAPDEL= map-name
removes the specified map from global memory. A map that is not in memory is
shown as NAMEONLY by the SHOW MAPS command.
A map is a set of definitions used by Mapping Services. Together, the definitions
in a map describe the entire structure of some item of data. Data described by
maps are placed in mapped data object (MDO) variables used in NCL processes.
NCL uses maps to interpret the data in these variables.
Considerations
This system parameter is not included in the display from the SHOW SYSPARMS
command or the display from the Display/Update SYSPARMS Settings option in
System Support Services.
Removing a map from memory forces NCL to access the map on disk each time
the map is required. This can impede the performance of NCL processes that
access the map.
Example
The following example removes the map $MSG from memory:
SYSPARMS MAPDEL=$MSG
