Application Creation
Properties
Parsing is used when the developer needs to analyze or separate the data input into more
easily processed components. The parsing options are illustrated in Figure 8. The parsing
options available allow the developer to add a suffix or prefix. Additionally, Optimizer can setup
the data length to be a fixed length and pad the data if necessary. The Bar code Input can
enable the Optimus to read partial codes, verify check digits, and setup how the data should be
entered.
Figure 8 Properties Options
Fixed data length
Click on the checkbox to activate this option. This setting sets the allowable length of the
data collected to a fixed length. The developer determines that length by the number
entered in the field. Any data entered into this field that is greater than the specified value
will be truncated. For data entered that is less than the specified value, spaces or '0's will be
added in front of or end of the transaction data depending on the "Left" or "Right" alignment.
The alignment is determined by the drop down menu (see Figure 8). If the checkbox is
unchecked, the data length of this field is unstructured. The
Form data field will instead be
bound by the data type and minimum length and maximum length specified for this input
field.
Initial value or text
This setting specifies whether or not there will be an initial value or text for this field.
