EXITS Statement
EXITS Statement (for Experienced)
Summary
For basic information, go through the Control Statements (for Beginners)
The EXITS statement is used to identify exit routines IEBGENER to use.
Syntax -
//SYSIN DD *
EXITS [INHDR=routinename][,OUTHDR=routinename]
[,INTLR=routinename][,OUTTLR=routinename]
[,KEY=routinename][,DATA=routinename]
[,IOERROR=routinename][,TOTAL=(routinename,size)]
/*Parameters -
| Keyword | Description |
|---|---|
| INHDR=routine-name | Specifies the name of the user header routine (input). |
| OUTHDR=routine-name | Specifies the name of the user header routine (output) that creates. |
| INTLR=routine-name | Specifies the name of the user trailer routine (input). |
| OUTTLR=routine-name | Specifies the name of the user trailer routine that processes (output). |
| KEY=routine-name | Specifies the name of the output record key routine. |
| DATA=routine-name | Specifies the name of the physical record routine that modifies before IEBGENER processes it. |
| IOERROR=routine-name | Specifies the routine's name that handles permanent input/output error conditions. |
| TOTAL=(routine-name,size) | Specifies that a user exit routine is to be provided before writing each record. |
| routine-name | Specifies the name of the totalling routine. |
| size | Specifies totals, counters, pointers and so forth. |
Example -
Requirement - Split sequential file records into three PDS members along with PDS creation. The newly created members are merged into an existing partitioned data set.
Input PS File - MATEPK.IEBGENER.INPUTPS

****** **************************** Bottom of Data ****************************Explaining Example -
- SYSUT1 DD maps the input data set (MATEPK.IEBGENER.INPUTPS).
- SYSUT2 DD defines the output partitioned data set (MATEPK.IEBGENER.OUTPDS).
- SYSIN DD defines the control data set.
- GENERATE MAXNAME=3,MAXGPS=2 indicates a maximum of three names and two IDENTs are included in subsequent MEMBER statements.
- EXITS IOERROR=ERRORRT define the user routines to process user label for the IOERROR.
- MEMBER NAME=MEMBER1 names the first member as MEMBER1.
- RECORD IDENT=(5,'E0003',1) copies the records upto 'E0003' from the beginning to MEMBER1.
- MEMBER NAME=MEMBER2 names the second member as MEMBER2.
- RECORD IDENT=(5,'E0005',1) copies the records after 'E0003' until 'E0005' to MEMBER2.
- MEMBER NAME=MEMBER2 names the third member as MEMBER3 and copies the records after 'E0005' until end because no RECORD IDENT statement coded.
