Figure 1. CORE Format

CORE is used to override the installation default for the amount of memory the sort/merge is allowed to use. To specify an amount of memory, choose one entry from each pair of braces.

Note that CORE and SIZE are synonymous. Note also that memory specification may be a decimal number of bytes (CORE=n), a decimal multiple of K, where K=1024 bytes (CORE=nK), or a decimal multiple of M, where M=1048576 bytes (CORE=nM).

For simplicity, the following describes only CORE, specified in units of nK.

CORE=nK

Defines a maximum memory limit of nK below the 16-megabyte line.

CORE=MAX

Assigns to the sort/merge all the available memory above and below the 16-megabyte line.

CORE=MAX-nK

Assigns to the sort/merge all the available memory above and below the 16-megabyte line less nK bytes, which is reserved below the 16-megabtye line.

Consult your systems staff for any installation-specific modifications to the handling of CORE. For example, "CORE" will be limited if a maximum memory size for MFX was set at installation time.
