Supplying Dynamic Data for Incremental Fields
Incremental dynamic data fields are created in the Create Form mode using
the incremental alphanumeric or bar code commands. The incremental
dynamic data itself is supplied during the Execute Form mode at the top of
the form prior to any overlay data. The incremental dynamic data (either
alphanumeric or bar code data) can be changed with each new batch of
forms. Incremental dynamic data fields specified in the Create Form mode
will not appear on the form if corresponding incremental dynamic data is not
supplied in the Execute Form mode.
Format For incremental dynamic alphanumeric data:
(cc)IAFn; [idir] STEPMASK; [RPTn;] [RSTn;] (D)STARTDATA(D)
For incremental dynamic bar code data:
(cc)IBFn; [idir] STEPMASK; [RPTn;] [RSTn;] (D)STARTDATA(D)
(cc) The Special Function Control Character.
IAF Identifies the command as incremental alphanumeric
dynamic data; enter IAF.
IBF Identifies the command as incremental bar code
dynamic data; enter IBF.
n Identifies the field number of the dynamic data field as
entered in the Create Form mode. Replace n with the
number used to identify the field when it was defined.
idir The optional increment direction parameter to specify
an increase or decrease of the data. Enter a plus sign
(+) or leave the field blank to increment (the default).
Enter a minus sign (–) to decrement.
STEPMASK Defines the increment amount (step), the number of
character positions in the data field, and provides a
mask to control the increment function on specific
parts of the data. Refer to “Incremental Bar Code
Fields” on page 5–116 or “Alphanumerics, Incremental
Fields” on page 4–18 for complete information on
STEPMASK parameter values.
