2.2.1.1 Variable Names
All tags work with the names of environmental variables. These are passed either through the CGI interface when doing
HTML pages, and/or read from the stored environmental data. There are two types of variable names used by the
program:
Fixed Names:
The standard name with no additions, like AP_SSID
Indexed Names:
When variables are indexed by instance, they will typically have an extension, such as
AP_SSID_2. The indexed names are expressed as AP_SSID#, where the # is replaced by the
index as specified in the –t (translate) option
All variable names fall within these two categories. Indexed names can be used in any tag value
2.2.1.2 File Tags
The used tag types are designed to support two main efforts. First, they will allow an HTML page to be created with
tagged information that will be translated through the CGI interface. Secondly, in a command line format, it can be used
to manage the values stored in the flash/cache areas, allowing the user to have either temporary or permanent parameter
storage. Table 1 defines the available tags.

Tag
Usage
Example
~~VAR_NAME~
~~VAR_NAME#~
Direct replacement of the environmental
variable with its value. Variable must
exist to produce a value. If the value does
not exist, the tag is erased and no
characters are substituted.
~~AP_SSID~
~~AP_SSID#~
~~VAR_NAME:default~
~~VAR_NAME#:default~
Direct Replacement with Default. If the
variable exists, then its value is inserted.
If it does not exist, then the “default”
string will be substituted.
~~AP_STARTMODE:dual~
~~AP_CHMODE#:11NAHT20~
~`exec str`~
Execute the program or script enclosed in
` ` markers. The output of these programs
will be processed to be displayable in
HTML format (non breaking spaces will
be added, and tabs translated). Note that
any stderr output is not caught, and
should be piped to /dev/null if to be used
in a web page.
~`athstats 2>/dev/null`~
~cVAR_NAME:VAL~
~cVAR_NAME#:VAL
Used for checkboxes in HTML files
~sVAR_NAME:VAL~
~sVAR_NAME:VAL~
~?VAR_NAME:VAL`exec str`~
~?VAR_NAME#:VAL`exec str`~
