The following environment variables can be used for configuring SORT:
MFJSABCODE Used to override the default abend code when MFJSERET=ABEND is specified.
MFJSDCBOUTFIL Determines whether the DCB's LRECL value is honored during an OUTFIL statement. [3]
MFJSENGINE Determines which sort engine the utility MFJSORT is to emulate.
MFJSERET Determines the response to an unsuccessful sort, copy or merge operation.
MFJSLSEQFB During a JCL sort, line-sequential files are treated as variable-block. If you would like them to be treated as fixed-block
files, set MFJSLSEQFB=ON.
MFJSSTRICTSORT Enables strict mainframe emulation behavior during a sort.
MFJSTATS Produces a report for the COBOL SORT operation.
MFJSWINDOW Determines the sliding or fixed century window.
SORTCOMPRESS Determines whether to compress each record in a SORT operation.
SORTEXITREENTRY Determines whether E15 user exits will be called after the SORTIN data set has been exhausted. [9]
SORTSCHEME To increase performance of a SORT operation, configure SORT to retain more of the record information in memory.
SORTSPACE Determines the amount of memory allocated to internal workspace for SORT operations.
SORTTEMPSPACE Determines the amount of temporary memory allocated for SORT operations.
SORTTYPE Determines the method for reading and writing files during SORT operations.
TMPDIR/ TMP/ TEMP Determines where the run-time system of the directory stores paging files.
