RefProc

See Also: RefClass, RefFunc, RefProcSet, RefTable

Purpose

Allows referencing a procedure name in an undecorated manner.

Return Type

String

Syntax

(RefProc( {ProcedureName} ))

What it Does

In version of DataFlex prior to 15.1, there were certain places where procedure names had to be referenced using a decorated name, by prepending "msg_" to the procedure name. Using RefProc allows developers to use undecorated procedure names.

This makes referencing procedure names in such instances more intuitive as developers no longer need to know the special decorated naming convention and when to use it. The use of RefProc also allows for full CodeSense support in the Studio.

Example

For example, to specify a procedure to use for database save confirmation, you would have to use code like this:

Procedure CustomExit

End_Procedure

Set Exit_msg to msg_CustomExit

Now, you can do this instead:

Procedure CustomExit

End_Procedure

Set Exit_msg to (RefProc(CustomExit))

Notes

• RefProc can only be evaluated at compile time.

• RefProc cannot be used to reference messages that return values. The examples below are cases where the existing get_ and msg_ methodology must still be used.

Forward Get msg_ProcedureName {parameters} to Variable
Get msg_ProcedureName {parameters} to Variable
