To access LVAR use the prefix L:

(L:AB_MCP_AP_ON, Number)

To access FSUIPC Offsets use the Prefix F:

(F:0000:0AB2, Number)

X:VARNAME = Local var , will not be saved, will always be initialized to 0´ when profile loaded
G:VARNAME = Local var, Value will be saved to the GAUGE, loaded to that value again when the gauge is loaded
P:VARNAME = Local var , Value will be saved to the PROFILE , and loaded to that value when the profile is loaded (Exception (P:SIMULATION RATE,Number) and (P:UNITS OF MEASURE,Number) still work as expected.

All time variables as shown here can be used with the “X:”-Prefix to retrieve the local computer time as UTC/Local.
To get the local computer hour you would use

(X:LOCAL TIME,Hours)

The Image-Tag supports the following extensions for dynamically changing images:

• Attribute “Dynamic”
• Sub-tag “Value”

See: Example for dynamic images

To assign a function to a FIP button other than a SimConnect Control Event, you can deliver an extended button configuration together with your gauge.
Just configure the button as desired within SPAD.neXt, and then export the button configuration (copy to clipboard and save to a file) to a file BUTTONNAME.bml in the gauge main directory.
The following buttons are supported:
FIP_BUTTON_S1 - FIP_BUTTON_S6 , FIP_RIGHTDIAL, FIP_LEFTDIAL, FIP_BUTTON_PAGEUP, FIP_BUTTON_PAGEDOWN

SPAD.neXt also defines an additional tag for providing settings in a gauge:

<Gauge>
..
..
..
  <GaugeSettings .....>
  </GaugeSettings>
</Gauge>
