| length;IDFn;format; |
length | A decimal number specifying the bit |
| length of a field within a tag. The |
| maximum length for each DFn field is 64 |
| bits. |
DFn | 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. |
IDFn | 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 (/).
