COPY Operator (for Experienced)


Summary

For basic information, go through the COPY Operator (for Beginners)

  • COPY operator is used to copying an input file to one or more output files.
  • The output files can be up to 10.
  • If USING(XXXX) operand is specified, the DFSORT control statements are mandatory and should code as XXXXCNTL.
  • The control statements and other options are used to copy some from total input records, reformat records for output, etc.

Syntax -

Copy to single output file -

  COPY FROM(indd) TO(outdd)

Copy to multiple output files -

  COPY FROM(indd) TO(outdd1, outdd2, outdd3)

Copy to output file using a control card -

  COPY FROM(indd) TO(outdd) USING(xxxx)

Copy to output file using a control card without outdd (Control card should have OUTFIL FILES) -

  COPY FROM(indd) USING(xxxx)

Copy for fixed or Variable length VSAM Files -

  COPY FROM(vsamin) TO(vsamout) VSAMTYPE(V/F)

Copy for join keys with outdd -

  COPY JKFROM TO(OUT1) USING(xxxx)

Copy for join keys without outdd -

  COPY JKFROM USING(xxxx)
COPY Operator

Required Operands


FROM -

  • FROM parameter specifies ddname of the input file.
  • indd DD statement is mandatory if FROM operand specified.

JKFROM -

  • JKFORM is used for a JOIN KEYS application.
  • JKFROM is mandatory for USING(xxxx) operand.
  • In xxxxCNTL, a JOINKEYS statement should provide F1=ddname1 for the F1 file, F2=ddname2 for the F2 file, JOIN and REFORMAT statements according to the requirement.

TO -

  • TO operand specifies 1 to 10 ddnames of output files.
  • outdd DD statement is mandatory if TO operand specified
  • Either TO, USING, or both operands can code at the same time.

USING -

  • USING operand specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement file.
  • XXXX name is the user-defined name.
  • xxxxCNTL DD statement is mandatory if USING(xxxx) is specified.
  • Either TO, USING, or both operands can code at the same time.

Optional Operands


VSAMTYPE -

  • VSAMTYPE operand specifies the record format for a VSAM input file (F or V).

Example -


Scenario - Copy all the records from input file to output file.
