Tag identifier Meaning
FUNCTION_BODY Function body
The tag contains the function body of a subfunction. The function body needs to be program‐
med within the DialogGui tag.
Attributes:
● name = "Name of the function body"
● parameter = "Parameter list" (optional)
The attribute lists the transfer parameters that are required. The parameters must be
separated by a comma.
When the function body is called, the values of the parameters specified in the function
call are copied to the transfer parameters listed.
● return = "true" (optional)
If the attribute is set to true then the local variable $return is created. The function's return
value which is forwarded to the calling function on quitting the function should be copied
to this variable.
Syntax:

<FUNCTION_BODY name = "<function name>">
…
…
…
</ FUNCTION_BODY>

<FUNCTION_BODY name = "<function_name>" parameter = "<p1, p2, p3>">
