RANGE Operator (for Experienced)


Summary

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

  • RANGE operator displays a message with the count of values that are in between the coded range for a field.
  • The count message always prints in the TOOLMSG dataset.

Syntax -

RANGE Operator

Required Operands


FROM -

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

LIST -

  • listdd specifies the list dataset ddname to be created by ICETOOL LIST operation.
  • A listdd DD statement should be provided.

ON -

  • ON operator specifies the field(s) used for DISPLAY operation.
  • 1 to 50 ON fields can be specified with the DISPLAY operation.
    • (p,m,f) gives the position, length, and format of a numeric or character field. The field should not be beyond position 32752 or the end of the record.
    • (p,m,f, formatting) gives a numeric or character field's position, length, and format. It also specifies how the data is to be formatted for printing for this field. The field should not be beyond position 32752 or the end of the record.
    • VLEN is equivalent to ON(1,2, BI) for variable-length records, representing each record's record length.

HIGHER, LOWER, EQUAL, NOTEQUAL –

  • Defines the range for the values to be counted.
  • HIGHER and LOWER may be used together or separately.
  • EQUAL and NOTEQUAL should use separately.
  • x, y, v, and w should be specified as n, +n, or -n where n can be 1 to 31 digits.

Optional Operands


VSAMTYPE -

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

Example -


Scenario - Display the active employees count in between 2 and 6.
