Understanding Input Mask Characters |
When you define an input mask, you can enter characters that determine the type of data that will be accepted for each individual character, called control characters. You can also enter characters that will be displayed and/or printed with the data, called literal characters.
Control characters allow you to explicitly define the type of data that will be accepted for input in a specific character position. You can define each individual character position independently from the other characters in the input mask.
The following table describes the function of each of the control characters available for use in

Literal Characters are characters that display on the screen or print but do not affect the data. They are used to insert additional characters and symbols into the data that is received by
If you wish to use a control character as a literal character, you may do so by placing a back slash (\) immediately before the control character or placing a string of control characters within quotes.
By default, the literal characters in your input mask will be displayed on the template and printed on your items. However, sometimes you may want to display literal characters on the data entry, but do not want them to actually print on your items. You can so this by disabling the Print Literal Characters option. When disabled, the literal characters will be displayed in the corresponding reply boxes of the data entry form that is displayed upon execution of a print job.
