In this example, two groups of serial numbers (001234, 001235, 001236, and 001334, 001335, 001336) are placed on six tape volumes. The labels are written in EBCDIC at 800 bits per inch. Each volume labeled is mounted, when it is required, on a single 9-track tape unit.

  //LABEL3   JOB  ...
  //STEP1    EXEC PGM=IEHINITT
  //SYSPRINT DD  SYSOUT=A
  //LABEL    DD  DCB=DEN=2,UNIT=(tape,1,DEFER)
  //SYSIN    DD  *
  LABEL   INITT   SER=001234,NUMBTAPE=3
  LABEL   INITT   SER=001334,NUMBTAPE=3

The control statements are as follows:

• LABEL DD defines the tape unit to be used in the labeling operation.
• SYSIN DD defines the control data set, which follows in the input stream.
• LABEL INITT defines the two groups of serial numbers to be put on six tape volumes.
