2. If applicable, enter a mask value in the Keep bar codes with mask field.
The Keep bar codes with mask option should be used when one or more
Anywhere bar code zones are defined. The bar code value is only retained
for the defined zone when it complies with the mask specified in the Keep
bar codes with mask field. This ensures that the bar code values read on a
page get assigned to the correct bar code zone.
This option is also useful when more than one Zone bar code zones are in
the same physical location on a page but have different values and
meanings (e.g., a zone defined for a batch header sheet versus a zone
defined for a document header sheet). To comply with a specified mask,
each character of the bar code value must match the mask syntax for that
character’s position in the mask.
For example, a mask of A(8) will retain a bar code value of up to, but not
exceeding, eight alphabetic characters:
Bar Code Value Retained?
SURGERY Yes
ADMISSION No
See the “Mask syntax” section in Chapter 4 for mask syntax values.
3. Enter the minimum length of the bar code.
By default, the minimum length is set to the length of the tested bar code
value. If a value is not found or the value is equal to or greater than six
characters, the default will be set to “6.” It is recommended that the
Minimum length parameter be set at 6 characters or fewer to allow
Capture Software to retain bar code values in cases of a partial read.
NOTE: If Partial Reading is not required or enabled, then the mask and
minimum length settings can be used in combination to restrict
even further the bar code values that are retained. For example:
Mask 9(10)
Minimum bytes 6
retains bar code values between six and ten digits, while
Mask 9(10)
Minimum length 10
retains bar code values only if they are exactly ten digits.
