Your presentation must look in this way:
//STEP0010 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
DELETE (TMAK.SYSREC.T0050TEP.NRTBE) NVSAM
DELETE (TMAK.SYSPUN.T0050TEP) NVSAM
IF MAXCC=8 THEN SET MAXCC=0
/*
//STEP0020 EXEC DSNUPROC,SYS='D2BB'
//*
//SYSREC DD DSN=TMAK.SYSREC.T0050TEP.NRTBE,
// DISP=(,CATLG,DELETE),
// SPACE=(CYL,(200,100),RLSE),AVGREC=U
//*
//SYSPUNCH DD DSN=TMAK.SYSPUN.T0050TEP,
// DISP=(,CATLG,DELETE),
// SPACE=(CYL,(200,100),RLSE),AVGREC=U
//*
//SYSIN DD *
UNLOAD DATA FROM TABLE ANJA1E.T0050TEP;
WHEN (STICHTAG = '2021-02-23')
/*
I demonstrates, that you have not a minor idea how things work.
1) The step with IDCAMS has no direct relation to the unload operation itself; it cannot affect the way to resolve your issue.
2) The UNLOAD operation provided by DSNUPROC procedure is extremely limited in available options to control the output dataset format.
3) The semicolon at the end of the first UNLOAD statement line seems to be either syntax error, or misleading.
4) When using DSNUPROC/UNLOAD you may need one extra step (of SORT utility, or FILEAID, or whatever else), - to convert output data format(s) to what you really need.
5) The //SYSPUNCH DD defines the dataset to save an optional LOAD statement, for future reload of unloaded data back to DB2 tables. It needs to be RECFM=FB,LRECL=80, and its maximum possible SPACE=(TRK,(1,1)), but not SPACE=(CYL,(100,200))
6) Since you are not going to re-load the data back to DB2, but instead planning to convert data format(s), the //SYSPUNCH DD dataset is not required at all.
7) More convenient way to unload data in printable format would be using other utilities, like DSNTIAUL, or HPU (PGM=INZUTILB, High Performance Utility), or FileAid/DB2, or others, which do have their own options to specify the unloaded fields formats.
8) None of JCL options can affect the way how DB2 table is unloaded; this is 100% internal issue of the utility used to unload data.
Unfortunately, from the first sight it's getting clear that the presented example of JCL code has been copied-and-pasted from unknown source, without a minor attempt to understand it...
