COUNT operator prints the count of records in a file and sets the return code based on the criteria match.

Syntax -

Count all records in the input file -

  COUNT FROM(indd)

Count using DFSORT control card -

  COUNT FROM(indd) USING(xxxx)

Setting RC using parameters -

  COUNT FROM(indd) EMPTY

Sets RC=12 if indd file is empty (indd has no records), or sets RC=0 if indd is not empty (indd has at least one record). Similarly for NOEMPTY, HIGHER, LOWER, EQUAL, NOTEQUAL parameters.

Setting RC explicitlt using parameters -

  COUNT FROM(indd) HIGHER(1000) RC8 USING(xxxx)

Sets RC=8 if more than 1000 records are selected from indd based on control card USING(xxxx), or sets RC=0 if 1000 or fewer records are included from indd.

Creating custom record with the count -

  COUNT FROM(indd) WRITE(count) -
  DIGITS(d)  - 
  WIDTH(record-length)

Creating custom record with the count and user-defined text -

  COUNT FROM(indd) WRITE(count) TEXT('string') -
  DIGITS(d) | EDCOUNT(fromatting) - 
  WIDTH(record-length)

Required Operands

• FROM - FROM parameter specifies ddname of the input file.

Optional Operands

• USING - USING operand specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement file.
• VSAMTYPE - VSAMTYPE operand specifies the record format for a VSAM input file (F or V).
• EMPTY - Sets RC=0 if the input file or subset is empty.
• NOTEMPTY - Sets RC=0 if the input file or subset is not empty.
• HIGHER (x) - Sets RC=0 if the record count is equal to or lower than x.
• LOWER (y) - Sets RC=0 if the record count is equal to or higher than y.
• EQUAL (v) - Sets RC=0 if the record count is not equal v.
• NOTEQUAL (w) - Sets RC=0 if the record count is equal w.
• RC4 - RC4 is used to set RC=4 if the record count satisfies the specified criteria.
• RC8 - RC8 is used to set RC=8 if the record count satisfies the specified criteria.
• RC12 - RC12 is used to set RC=12 if the record count satisfies the specified criteria.
• SUB (q) - Subtracts a value from the derived record count.
• ADD (r) - Adds a value from the derived record count.
• WRITE (countdd) - Specifies the ddname of the count file created by ICETOOL for this operation.
• TEXT - Specify a string that is to be printed before the output records count.
• DIGITS (d) - Specify the number of digits for the count in the output count file.
• EDCOUNT (fromattling) - Specifies how the count is to be formatted for printing.
• WIDTH (n) - Specifies the record length and LRECL for the count file.

Example -

Scenario - Count the employee records whose country is 'IN' (from 60th byte of length 2) to output dataset.
