In this example, a member (MODMEMB) is updated within the space it actually occupies. Two existing logical records are replaced, and the entire member is renumbered.

  //UPDATE   JOB  ...
  //STEP1    EXEC PGM=IEBUPDTE,PARM=MOD
  //SYSPRINT DD  SYSOUT=A
  //SYSUT1   DD  DSNAME=PDS,UNIT=disk,DISP=(OLD,KEEP),
  //             VOLUME=SER=111112
  //SYSIN    DD   *
  ./     CHANGE   NAME=MODMEMB,LIST=ALL,UPDATE=INPLACE
  ./     NUMBER   SEQ1=ALL,NEW1=10,INCR=5
 
  (Data statement 1, sequence number 00000020)
  (Data statement 2, sequence number 00000035)
 
  /*

The control statements are as follows:

• SYSUT1 DD defines the partitioned data set that is updated in place. (Note that the member name need not be specified in the DD statement.)
• SYSIN DD defines the control data set, which follows in the input stream.
• The CHANGE function statement indicates the name of the member to be updated (MODMEMB) and specifies the UPDATE=INPLACE operation. The entire member is listed in the message data set. Note that, as renumbering is being done, and since UPDATE=INPLACE was specified, the listing would have been provided even if the LIST=ALL parameter had not been specified. See the LIST parameter for more information.
• The NUMBER detail statement indicates that the entire member is to be renumbered, and specifies the first sequence number to be assigned and the increment value (5) for successive sequence numbers.
• The data statements replace existing logical records having sequence numbers of 20 and 35.
