length
A decimal number specifying the bit
length of a field within a tag. The
maximum length for each DFn field is 64
bits.
DF
n
Optional parameter to indicate this field
has dynamic data. Replace
n
with a
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.
NOTE: 1. The same field number cannot be used in both DFn and
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.
format
A letter specifying the format of the data field.
B – binary, D – decimal, H – hexadecimal
(D) 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 (/).
