DFT (Default) keyword in printer files

You use the DFT keyword to specify constant values for constant fields.

The format of the keyword is:

DFT('value')
'value'
DFT(X'hexadecimal-value')
X'hexadecimal-value'

Constant values can be:

A character value, in which each character prints as you specify it. The number of characters is equal to the printed length of the field. (Within the value, two adjacent single quotation marks are printed as one.) See example 1.
A hexadecimal value, in which two characters identify a code point in the character set. These characters print in this field (define alternate characters using DFNCHR). The printed length is half the number of characters you specify between single quotation marks. You must specify the TRNSPY keyword if you specify a hexadecimal value for DFT. See example 2.

You can specify DFT implicitly by omitting DFT and the parentheses (this is true for both character and hexadecimal values). Specify the value within single quotation marks. For hexadecimal values, you must also precede the value with an X.

The EDTCDE and EDTWRD keywords cannot be specified with the DFT keyword.

Option indicators are not valid for this keyword. However, they can be used to condition the constant field with which this keyword is specified, specifying the last option indicator on the same line as the field location.

Example 1

The following example shows how to specify DFT using character values.

|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
00010A          R SUPPLIES
00020A            PENS          20      2  1
00030A            INK           20      3  1
00040A            PAPER         20      4  1
00050A                                  7  9DFT('ON')
00060A                                  8  9'ON'
00070A
00080A  01                             12  1'Hotel name: 'Terrace Inn'
00100A
00110A  02                             12  1'Hotel name: 'Riverview Inn'
     A

The specifications DFT('ON') and 'ON' are equivalent and show the difference between specifying DFT explicitly and implicitly.

If indicator 01 is on, this prints:

Hotel name: 'Terrace Inn'

If indicator 02 is on and indicator 01 is off, this prints:

Hotel name: 'Riverview Inn'

Example 2

The following example shows how to specify DFT for a constant field containing an alternate character.

|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
12
00010A          R RECORD                    DFNCHR(X'7C' X'007E813CC324817E00')
00020A                          358  4DFT(X'7C')   TRNSPY  4
00030A                                    +2DFT('1982')
     A

The constant field for which DFT is specified 1 appears on line 58, position 4. The character defined for hexadecimal 7C prints in this field. DFNCHR 2, specified at the record level for this example, defines hexadecimal 7C as a copyright mark.

Here are some equivalent ways to specify the value as defined in this example 3:

DFT(X'7C')
X'7C'
DFT('©')
'©'

The TRNSPY keyword 4 is required when hexadecimal values are specified for DFT.
