number ranging from 1 to 512 to identify
the field number of this particular field. If
this option is used, datafield is ignored,
and dynamic data must be entered via the
DF command in the EXECUTE mode.
IDF n Enter IDF to indicate this field is a bit field
with dynamical assignment of increment
(or decrement) data. The step and
startdata parameters will be supplied by
the IDF command in the EXECUTE mode.
Replace n with a number ranging from 1 to
512 to identify the field number of this bit
field. Dynamically enter the step and
startdata parameters using the IDF
command in the EXECUTE mode.
IDFn.
2. If a field is defined as IDFn, it must be referenced as
IDFn later for consistency. The same applies for DFn.
3. If <IDFn> syntax is used for merging data into AFn or
BFn, neither DFn, AFn, or BFn will be incremented. The
increment only takes place in the ~DFn command where
the STEP is specified.
A letter specifying the format of the data field.
B – binary, D – decimal, H – hexadecimal
Delimiter designating the start and end of static data for
this bit field. Replace (D) with any printable character,
except the SFCC and the slash character (/).
The static data of this static field. It is a mandatory
parameter of bit field with static data.
Identifies this field is an incremental bit field.
Specifies that the incremental data field will use the
step method. Enter STEP;. The STEP option replaces
the STEPMASK option that is used in Alpha and
Barcode.
Enter a plus sign (+) or leave the field blank to
increment (default). Enter a minus sign (–) to
decrement.
