DDS for display files

Name for display files (positions 19 through 28)

Use these positions to specify record format names and field names.

Refer to the DDS Reference: Concepts information for rules to use when specifying record or field names in DDS.

The names must begin in position 19.

Figure 1 shows you how to specify record format names and field names.

Record format name:

When you specify R in position 17, the name specified in positions 19 through 28 is a record format name. You can specify more than one record format for a display file, but each record format name must be unique within that file.

Field name:

When position 17 is left blank, the name you specified in positions 19 through 28 is a field name. Field names must be unique within the record format.

Constant fields:

Constant fields are unnamed fields (positions 19 through 28 must be blank). The following rules apply to constant fields:

How to determine the order of fields in a record format:

The order of the name fields that you specify in a record format is the order in which the name fields appear in your program when it is compiled. (Unnamed fields do not appear in your program.)

The locations of named and unnamed fields you specify in positions 39 through 44 determine the order that the fields appear in the display. See "Location for display files (positions 39 through 44)". Hidden fields (H in position 38) and Program-to-System fields (P in position 38) do not appear on the display.
