WRKCACHE=n| nK | nM | nG | MIN | MAX | hexX

n | nK | nM | nG: specifies the size of the data cache in bytes (n), kilobytes (nK), megabytes (nM), and gigabytes (nG).
MIN: sets the size of the I/O data cache to 0.
MAX: sets the size of the I/O data cache to 65024. This number is the default.
hexX: specifies the size of the I/O data cache as a hexadecimal number. This number must be followed by an X, as in hexadecimal-valueX.

Details

The WRKCACHE= system option controls the size (in bytes) of the data cache used to buffer I/O pages for files that are created in the WORK data library. This option functions exactly like the CACHESIZ= data set option, which you can use in a LIBNAME statement. However, because no LIBNAME statement is explicitly issued for the WORK data library, the WRKCACHE= system option is necessary to enable you to specify a default cache size for all files that are created in the WORK data library by the V8, V8TAPE, V7, V7TAPE, V6, or V6TAPE engines. The value of n must be a positive integer.
