BEE Script:   parent var;

BEE Tag:     <beeparent "var">

The "parent" command is valid only within a function. It declares that a variable is equivalent to the one in the "parent" (the calling function's Context), which means that the variable inherit the value set before the function call, and any changes to them inside the function survive the exit of it.

In another word, "parent" variables are references to the caller's variables.

However, if the function calls another function, the "callee" function would not see the variables declared "parent" in the "caller" function, unless the "callee" declares these variables "parent" as well.

If the variable name var is missing, the whole Context (all variables in the parent Context) will be linked with the one of the parent.  (Please use this carefully to avoid polluting the parent's environment.)
