Alphanumerics, Incremental: Dynamic Data Fields
Purpose Automatically increments/decrements dynamic alphanumeric
data fields. Specifies the location and size of the incremental
dynamic data field during the Create Form mode. STEPMASK
and STARTDATA parameters are supplied in the Execute
command during the Execute Form mode.

IAFn;L Identifies this alphanumeric command as an
Incremental Alphanumeric Dynamic Data Field
command. The command parameter string
identifies the incremental dynamic data field
location on the form and defines the length of the
alphanumeric data. If these parameters are used,
the STEPMASK and STARTDATA parameters can
not be entered in the Create Form mode; they are
entered dynamically during the Execute Forms
mode. To use the incremental dynamic data field,
perform the following steps:
a. Enter IAF to specify an incremental
alphanumeric dynamic data field.
b. Replace
n
with a number ranging from 1
through 512 to identify the alphanumeric string
location on the form. The standard
alphanumeric SR and SC command
parameters specify the exact location of the
field identified by
n
.
c. Replace
L
with a number equal to the number
of characters in the dynamic alphanumeric
string (STARTDATA) ranging from 1 through
280.
d. Dynamically enter the STEPMASK and
STARTDATA parameters in the Execute Form
mode. The length of the data must be equal to
or less than the value assigned to the length
(L) parameter. Refer to “Execute Form:
Incremental Dynamic Data” on page 65 for
more information.
Note In the command format below, incremental alphanumeric
command parameters are shown in boldface type; standard
alphanumeric command parameters and optional
nonincremental parameters are shown in

italics.
