In this example, serial numbers 001234, 001235 and 001236 are placed on three 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.

  //LABEL1   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
  /*

The control statements are as follows:

• LABEL DD defines the tape unit used in the labeling operation.
• SYSIN DD defines the control data set, which follows in the input stream.
• LABEL INITT specifies the number of tapes to be labeled (3), beginning with 001234.
