How do I sort a file with DFSORT? Tiny example?

Need to sort a FB file by account number in columns 1-8. Is this a whole COBOL program or can JCL do it?

JCL + DFSORT. Roughly:

//SORT STEP EXEC PGM=SORT
//SORTIN DD DSN=your.in,DISP=SHR
//SORTOUT DD DSN=your.out,DISP=(NEW,CATLG,DELETE)...
//SYSIN DD *
SORT FIELDS=(1,8,CH,A)

Ask ops for a sample with your site's SPACE defaults filled in.

CH = character. If it is packed decimal the format code changes. Start with CH for practice files.
