LABELS Statement

LABELS Statement

The LABELS statement is used to decide whether the labels are to copied or not to the output file. It is used when -

  • no user labels are to be copied.
  • user labels are to be copied from the SYSIN control card.
  • 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 -

DATA=ONLYSpecifies only user header labels are treated as data.
DATA=INPUTSpecifies user labels for the output file are coded as 80-byte input records in the data portion of SYSIN.
