Scope of Reference Statements
Most statements that reference fields and table fields are local in scope and apply to the form associated with a particular frame. Two statements used for passing data to other frames and procedures allow you to reference fields in other frames. You can also use these statements to reference local variables declared as parameters in the initialize statements of other frames.
• The callframe statement, used to pass data to another frame, allows you to pass data from fields and local variables to another frame.
• The callproc statement, used to pass data to another procedure, allows you to pass data from fields and local variables to a procedure.
You can reference global variables and constants from any frame or 4GL procedure. 3GL procedures can reference any form after it has been displayed.
