===== CALL ✓ =====

===== SYNTAX =====
     CALL name
     CALL name[par1 [,par 2 [, ....]]]

==== PURPOSE ====



The ''CALL'' keyword Transfers control to a routine. The first parameter is the
procedure to call. The procedure can be called using a list of variables or 
expressions representing arguments passed to the procedure when it is called. 
Multiple arguments are separated by commas. If you include prameters, you must 
enclose it in parentheses.

You can use the CALL keyword when calling a procedure. For most procedure calls, it is 
not necessary to use this keyword. Typically you use the CALL keyword when the called 
expression does not begin with an identifier. 

If the procedure returns a value, the calling statement deletes it.



==== EXAMPLE ====
    CALL factorial(42)
