LABELS Statement
LABELS Statement (for Experienced)
Summary
For basic information, go through the Control Statements (for Beginners)
The LABELS statement is used to decide whether the labels are to copied or not to the output data set. All but the last statements are ignored if more than one valid LABELS statement is coded.
The LABELS statement is used when -
- no user labels are to be copied.
- user labels are to be copied from the SYSIN data set.
- user labels are to be copied after the user's label processing routines modify them.
Syntax -
//SYSIN DD *
LABELS [DATA={YES|NO|ALL|ONLY|INPUT}]
/*Parameters -
| Keyword | Description |
|---|---|
| DATA=YES |
|
| DATA=NO | Specifies user labels are not required to treat as data. |
| DATA=ALL | Specifies that all user labels in the current processing group are required to treat as data. |
| DATA=ONLY | Specifies only user header labels are required to treat as data. |
| DATA=INPUT | Specifies user labels for the output data set are coded as 80-byte input records in the data portion of SYSIN. |

******************************** 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 MAXFLDS=3,MAXLITS=10 indicates a maximum of three fields and 10 literals are included in RECORD statements.
- RECORD FIELD=(5,'=====',,1) specifies the '=====' should filled in the output file from 1-5 positions.
- FIELD=(70,1,,6) specifies the input data (1-70 positions in input file) filled from 6th column(in output file).
- FIELD=(5,'=====',,76) specifies the '=====' should filled in the output file from 76-80 positions.
- LABELS DATA=INPUT specifies that the labels are included in the input.
- RECORD LABELS=3 specifies that 3 header lables should copy to output.
- .A .B .C specifies the header lables that should copy to output.
- RECORD LABELS=2 specifies that 2 footer lables should copy to output.
- .D .E specifies the footer lables that should copy to output.
