SORTWRK INCLUDE JCL block is a standard Data Definition for 5 sort working data sets. This definition repeats over and over again for every job step executing the program which performs system sort (typical example is a COBOL program performing internal sort). |
|
|
Like any other INCLUDE it is simply a shorthand, which permits to substitute several lines of the newly typed or Cut-n-Pasted operators for one line referring to a tested and reliable JCL block. Any number of INCLUDE statements can be coded in a job, provided that their names are unique within the job. For example of INCLUDE usage see the SORTSEQ cataloged procedure. |

Up to 100 CYLinders of fast Virtual Input/Output (VIO) storage looks quite sufficient for most standard sorts and can be adjusted at a single point of control — SORTWRK block. If only an Ad Hoc adjustment is necessary it's easy to Cut-n-Paste SORTWRK where necessary and adjust accordingly. |
