COBOL Manual for TNS/E Programs (H06.08+, J06.03+)

◦ INDEX-SLACK
specifies a percentage of slack space in each index block for an indexed output file. It
is applicable only if one GIVING file is specified and that file is an indexed file.
The value of param-value is in the range 0 through 99. The default is 0.
subsort-or-file-number must not be specified or must be 0.
◦ MINSPACE
specifies whether FastSort is to operate in the MINSPACE mode; that is, whether FastSort
should attempt to restrict the use of physical memory at the expense of sort time.
Meaning
Allowable Value for
param-value
FastSort uses up to 50% of the available physical memory. This may result
in loss of overall system performance if the system is busy.
0 (default)
FastSort uses a 64-page extended memory area.nonzero
See the FastSort Manual for details.
subsort-or-file-number must not be specified or must be 0.
◦ MINTIME
specifies whether FastSort is to operate in the MINTIME mode; that is, whether FastSort
should attempt to reduce execution time at the expense of physical memory.
Meaning
Allowable Value for
param-value
Operation is similar to MINSPACE mode.0 (default)
Up to 70% of the available memory will be used.nonzero
See the FastSort Manual for details.
subsort-or-file-number must not be specified or must be 0.
◦ NOPURGE-OUTPUT
specifies whether FastSort is to purge an existing output (GIVING) file if it seems too small.
Meaning
Allowable Value for
param-value
FastSort purges an existing GIVING file that seems too small before writing
the new data to it.
0 (default)
FastSort does not purge an existing GIVING file that seems too small unless
it has the wrong file type or wrong record length.
nonzero
subsort-or-file-number must not be specified or must be 0.
