This compiler option will allow you to control what the compiler will do with local variables, parameters and return types without type specification.

The default is -vo15+ for the VO and Vulcan dialects. For the Core dialect the default is -vo15-

Syntax

-vo15[+|-]

Arguments

+ | - Specifying +, or just -vo15, tells the compiler to treat untyped locals and return types as USUAL

To set this compiler option in the Visual Studio development environment:

 

1.Open the project's Properties page.

2.Click the Dialect tab.

3.Change the value.

4.Click here to see the property page

Example

FUNCTION LongSquare(nLong as LONG)      -/ Note that the return type is missing
 
RETURN nLong * nLong
 

 

In VO/Vulcan mode this will (by default) generate a method with a USUAL return type. In Core mode this will not compile but produce a "Missing Type" error (XS1031)

 

When you compile with -vo15- this will also produce an error.

 

Similar code that will be influenced by this compiler option

 

FUNCTION MultiplyLong(nParam1 as LONG, nParam2) AS LONG -/ Note that the type for nParam2 is missing
RETURN nParam1 * nParam2

And

FUNCTION Tomorrow() AS Date
LOCAL dToday := Today()          -/ Note that the AS DATE is missing
RETURN dToday + 1
