_Added in 1.8.8_ 

 */var [-gns] [-sg] <%var> [[= ]value]* 

 Sets the value of local variable %var to the specified value. 

 Syntax can be either _var %var = value_ or _var %var value_. 

 Multiple variables can be set in one line using comma as separator, _var %var1 = value, %var2 = value2_. 

 *Switches* 

 -s - Display variable assignment value. 
 -g - Creates a global variable instead. 
 -n - Treat the value as plain text, even if arithmetic operators are used. 

 *Parameters* 

 <%var> - The variable to set. 
 [[= ]value] - Value to set the variable to. (can be a single arithmetic expression, see [[Arithmetic Operators]]) 

 *Example* 

 <pre> 
 alias factorial { 
   var %result = 1, %x = $1 
   while (%x) { 
     var %result = %result * $v1 
     dec %x 
   } 
   return %result 
 }
