BYVAL Clause
 
Syntax
  BYVAL variable [AS type]
 
The BYVAL attribute in the parameter list of a DECLARE statement causes
the value of the specified variable to be passed to the procedure, rather
than the variable's address. BYVAL can only be used in DECLARE statements
for non-BASIC procedures, and cannot be applied to string parameters.
