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 field 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 field with no overflow
value is set or no more fields remain (i.e. reached first field).
If a character is typed and that character appears 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 enter "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.
Input mask output examples
The following are some common input masking examples:
URL Resources
A URL can be broken into several parts. For example, with 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/IP 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.
Special Escape Sequences
The system has only a limited knowledge of URL formats, as 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.
