| 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. |
