Declares a procedure or a function contained in a Dynamic Link Library (DLL).

Name is the name of the procedure or function.

LibName is the name of the DLL in which the procedure or function resides.

AliasName is the name under which the procedure or the function is exported from the DLL. If AliasName is omitted, it will be the same as Name. An alias is required, for example, if the exported name is a reserved name in SoftMaker Basic or contains characters which are not allowed in names.

Type specifies the data type (String, Integer, Double, Long, Variant). Alternatively, the type can be indicated by appending a type suffix (e.g. % for Integer) to the function name (see the section Data types).

The Declare statement can be used only outside of Sub and Function declarations.
