Input Mask Literals - AMX TPI-PRO-2 Operation/Reference Manual

Input Mask Literals

To define a literal character, enter any character, other than those shown in the above table (including spaces,
and symbols). A back-slash ('\') causes the character that follows it to be displayed as the literal character. For
example, \A is displayed just as the letter A. To define one of the following characters as a literal character,
precede that character with a back-slash. Text entry operation using Input Masks.
A keyboard entry using normal text entry is straightforward. However, once an input mask is applied, the
behavior of the keyboard needs to change to accommodate the input mask's requirement. When working with
masks, any literal characters in the mask will be "skipped" by any cursor movement including cursor keys,
backspace, and delete.

When working with ranges specified by the [] mask, the keyboard allows you to enter a number between the
values listed in the ranges. If a user enters a value that is larger than the max, the maximum number of
right-most characters is used to create a new, acceptable value.


When data overflows from a numerical field, the overflow value is added to the previous field on the chain, if
the overflow character was specified.
In the above example, if the overflow flag was set, the first example will place the "1" into the previous logical
field and the second example will place "12" in the previous logical field. If the overflow filed already contains
a value, the new value will be inserted to the right of the current characters and the overflow field will be
evaluated. Overflow continues to work until a filed with no overflow value is set or there are no more fields left
(i.e. reached first field).
If a character is typed and that characters appear in the Next Field list, the keyboard should move the focus to
the next field. For example, when entering time, a ":" is used as a next field character.
If you hit "1:2", the 1 is entered in the current field (hours) and then the focus is moved to the next field and 2
is entered in that field.
When entering time in a 12-hour format, entry of AM and PM is required. Instead of adding AM/PM to the
input mask specification, the AM/PM should be handled within the NetLinx code. This allows a programmer
to show/hide and provide discrete feedback for AM and PM.

When operating with a mask, the mask should be displayed with placeholders.
The "-" character should display where you should enter a character.
The arrow keys will move between the "-" characters and allow you to replace them.
The text entry code operates as if it is in the overwrite mode.
If the cursor is positioned on a character already entered and you type in a new (and valid)
character, the new character replace the old character.
There is no shifting of characters.
Example 1: If you type "125" into a field accepting 0-100, then the values displayed will be "1",
"12", "25".
Example 2: If the max for the filed was 20, then the values displayed will be "1", "12", "5".
