It JCL is as follows
| Code: |
//STEPXX EXEC PGM=SELECT
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=A.B.C.D,DISP=SHR
//SYSUT2 DD X.Y.Z,DISP=(OLD,CATLG)
////SYSIN DD *
MAXDEFS 2
A1 133 4 EQ EB12
A2 133 4 EQ EQ01
*** A1 *** A2 ***

I too have never heard of this utility, however it looks a little like an old 4gl called DYL260. Just as a guess I'd say that this program is selecting records from file A.B.C.D and writing them to file X.Y.Z.
Using an educated guess, I further surmise that it is potentially looking at an offset of 133 in the input record, for a length of 4 bytes and selecting records that contain either 'EB12' or 'EQ01' at that offset. Might take a look at the output file, and see if that is in fact the case. The EQ probably stands for EQUAL, so it is possible that it also uses "LT", "LE", "GT", "GE" and "NE".
It is very likely that the parameter coding is positional, meaning that the information has to be in a specific column.
