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 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.
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.
Example 1: If you type "125" into a field accepting 0-100, then the values displayed will be "1", "12", "25".

Example2: If the max for the filed was 20, then the values displayed will be "1", "12", "5".

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.

URL Resources

A URL can be broken into several parts. For example: the URL http://www.amx.com/company-info-home.asp. This URL indicates
that the protocol in use is http (HyperText Transport Protocol) and that the information resides on a host machine named
www.amx.com. The image on that host machine is given an assignment (by the program) name of company-info-home.asp (Active
Server Page). The exact meaning of this name on the host machine is both protocol dependent and host dependent. The
information normally resides in a file, but it could be generated dynamically. This component of the URL is called the file
component, even though the information is not necessarily in a file.
A URL can optionally specify a port, which is the port number to which the TCP connection is made on the remote host machine. If
the port is not specified, the default port for the protocol is used instead. For example, the default port for http is 80. An alternative
port could be specified as: http://www.amx.com:8080/company-info-home.asp.
NOTE: Any legal HTTP syntax can be used.

Special escape sequences

The system has only a limited knowledge of URL formats in that it transparently passes the URL information onto the server for
translation. A user can then pass any parameters to the server side programs such as CGI scripts or active server pages. However;
the system will parse the URL looking for special escape codes. When it finds an escape code it replaces that code with a particular
piece of panel, button, or state information.
For example, "http://www.amx.com/img.asp?device=$DV" would become "http://www.amx.com/img.asp?device=10001". Other
used escape sequences include:
