Demo Version of the SORT for TOS

A fully function demo version can be obtained by downloading a demo agreement, filling out the agreement, signing it and faxing it to me at 1-253-568-9630. I will email you an executable SORT with documentation that will expire at the end of the current month.

Sort/Merge Definitions and Options

The Sort/Merge program was designed to provide a subset utility for use within the Tachyon Operating System (TOS). It supports most of the standard options offered by IBM's DFSORT for MVS. Because it was designed to be run on a PC using TOS, the program creates Control Field Sort keys limited to a total length of 256 bytes. The keys are sorted into strings before the actual records are merged. Again, because of its design, the program does not support a number of DFSORT's options and will currently sort a maximum of 1.2GB of data for Production users and 1.0MB for Test/Development users. Moreover, the SORT must be executed as a job-step program and cannot be called via LINK or LOAD and CALL.

The following Sort/Merge statements are supported (SORT, MERGE and END).

The following Sort/Merge statements are recognized but not supported (ALTSEQ, DEBUG, INCLUDE, INREC, MODS, OMIT, OPTION, OUTFIL, OUTREC, RECORD and SUM).

When specifying SORT or MERGE the following Sort/Merge statements are supported (FIELDS, FORMAT, EQUALS, SKIPREC and STOPAFT). In addition, FILES=n is supported for SORT (n=1-9) to allow for input file concatenation. If FORMAT is used, please specify it before using the FIELDS statement.

When specifying SORT or MERGE the following Sort/Merge statements are recognized but not supported (CKPT, DYNALLOC, DYNALLOC=, NOEQUALS, FILESZ, SIZE and Y2PAST).

The following Control Field Formats are supported for SORT or MERGE (CH, ZD, PD, PD0, FI, BI, FL, AC, CSF or FS, CSL or LS, CST or TS, CLO or OL, CTO or OT, ASL, AST,Y2T, Y2U, Y2V, Y2W, Y2X, Y2Y, Y2C or Y2Z, Y2P, Y2D, Y2S and Y2B).

The following Control Field Formats are neither recognized nor supported for SORT or MERGE (AQ-Alternate Collating Sequence and D1-User Defined).

Future plans are to support limited subsets of INCLUDE and OMIT statements, limited subsets of callable SORT of MERGE capabilites, and 31-bit above the line programming.

The Sort/Merge JCL is the same as MVS JCL with a few exceptions. SORTIN, SORTWK01 thru SORTWK99 and SORTOUT are used for SORTS and SORTIN01 thru SORTIN99 and SORTOUT are used for MERGES. In addition, SORTIN02 thru SORTIN09 are used to support input file concatenation for the SORT. The RECFM, LRECL and BLKSIZE are extracted from the DCB SORTIN for the SORT or the DCB SORTIN01 for the MERGE and are used for all SORTWKnn's and for SORTOUT. The biggest exception is the use of SORTWK01 thru SORTWK99 as temporary datasets that must be defined for every SORT. The SORT's capacity is reduced as less SORT WORK files are defined.
