| 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. | |
