I was trying to explore IEBGENER utility
//DISKTODK JOB ...
//STEP1 EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=A
//SYSUT1 DD DSNAME=INSET,UNIT=disk,DISP=(OLD,KEEP),
// VOLUME=SER=111112,LABEL=(,SUL)
//SYSUT2 DD DSNAME=EXISTSET,UNIT=disk,DISP=(MOD,KEEP),
// VOLUME=SER=111113
GENERATE MAXNAME=3,MAXGPS=1
EXITS INHDR=ROUT1,INTLR=ROUT2
MEMBER NAME=(MEMX,ALIASX)
GROUP1 RECORD IDENT=(8,'FIRSTMEM',1)
MEMBER NAME=MEMY

in the above code, im not able to understand the meaning for
EXITS INHDR=ROUT1,INTLR=ROUT2
i is explained that exit routines

Exit routines are programs that are invoked at specific points during processing by the main program - in this case IEBGENER. Typically these are user routines that are used to enhance (hopefully) the processing. Different programs/utilities provide form different exit points and these should be specified in the program/utility documentation.
