Application Creation
Properties (Cont.)
Add prefix code
Setting adds a set string as a prefix to data entered in this field. Click on the checkbox to
activate selection.
Add suffix code
Setting adds a set string as a suffix to data entered in this field. Click on the checkbox to
activate selection.
Show input mark
Show input marks (for example, the underline character) in this field, indicating the maximum
length of the data required for the field.
Read partial bar code
By default the system will return the whole bar code that has been decoded. Activating this
setting enables the systems ability to use part of the bar code that is specified by the
settings. The starting position of each bar code defaults to 1, and the maximum length
defaults to 20.
Check leading code
The leading code check is used for verifying the bar code input. If the leading code is not
matched, the input bar code will be rejected.
Check Digit Verification
Check digit verification is a special check on a numeric or an alphanumeric field in which the
last (rightmost) character is a check digit. Verification can be either modulus 10 or modulus
11. Modulus checks are used when the risk of error keying in numbers must be reduced to a
minimum. The Optimizer has both available via the drop down menu under the Check Digit
Verification setting.
Auto ENTER
The auto ENTER setting automatically appends the data entered with a carriage return. The
developer can determine the location of the carriage return via the drop down box and have
the return after the data is entered (Scan + ENTER) or added before (ENTER + Scan) the
data so the user need not press the ENTER key to move to the next field.
Lookup
No lookup table is selected by default. The lookup setting will identify a specific field within the
available lookup table to be accessed. If the specified lookup field is the Primary key field in a
lookup table, all other input fields that form will be filled with the lookup data. A lookup field
prefixed with '+' means any data for that field will be updated to the original lookup data. A
lookup field prefixed with '-' means any added data for that lookup field will be subtracted from
the original lookup data. If you configure a lookup table in the lookup table menu it can be
assigned to a form.
