the same file name. Certain parameters can be reset to their default values, as indicated in the

discussion of the parameters below.

param-id

is one of:

CPU-MASK

SCRATCH-FILE

SWAP-FILE

NO-CPU-MASK

SORT-PROGRAM

param-text

is the identifier of an alphanumeric data item whose contents is used for the parameter specified

by param-id. If this parameter is omitted, any text previously set for this value of param-id

is reset to its default value.

The value of param-text depends on the value of param-id and sometimes on the value

of subsort-number (see Table 96).

subsort-number

is a numeric operand whose value specifies the sort process to which the parameter pertains.

The number of subsorts must have been set previously, and the specified subsort-number

must be in the range 0 to that number.

The value of subsort-number depends on the value of param-id (seeTable 96).

return-code

is an identifier of a numeric data item in which an error value will be returned. The expected

values and their respective meanings are:

MeaningValue

The call was correct.0

file-name does not name a sort-merge file.1

param-id is not one of the allowed values.2

param-text does not conform to the expected values.3

subsort-number was not within the range of the specified number of subsorts.4

Space for the options block cannot be allocated.5

Table 96 Relationship Between param-id, subsort-number, and param-text

param-textsubsort-numberparam-id

Contains a string of zeros and ones, with a maximum of 16

characters. The value of each character indicates whether a processor

Unspecified or 0CPU-MASK

is to be used for subsort processes for a parallel sort. The leftmost

character corresponds to processor 0, the next to 1, and so on, up

to processor 15. If there are fewer than 16 characters, the unspecified

ones are assumed to be 0.

If the value of the data item is “0” (ASCII zero), that processor will

not be used. If the value is “1,” that processor is a candidate for use.

Any other value is an error.

Default: All processors on the system are candidates for use.
