Saves (persists) variable value to a file.  The variable content can be later loaded again using <var_load> command.  The same file can be used for multiple (unlimited number) variables because each variable has its own section within the file.

Syntax: 

<var_save>("Variable", "File")

Variable
Variable to save value to file.

File 
The file to save variable value to.

Example:

<var_save>("vName","c:\_myvars.dat")
<varset>("vName=Michael","")
<var_load>("vName","c:\_myvars.dat")
<msg>(100,100,"vName","Message",1)
