EXTERNAL


Syntax:     EXTERNAL <procedure list>

Purpose:    To declare symbol(s) for the linker.

Argument:   <procedure list> is the list of procedures, user-defined
            functions, and format files to add to the symbol table.

Usage:      Procedures and user-defined functions referenced with a
            macro variable should be declared EXTERNAL to ensure that
            they are present at runtime.  Macro references to overlayed
            procedures or user-defined functions may not be properly
            resolved by the linker if they are not declared EXTERNAL.

            Compiling: EXTERNAL causes the linker to link the named
            procedures or functions even if they are not explicitly
            referenced in the source file.

Library:    CLIPPER.LIB

   EXTERNAL p1, p2, p3
   routine = "1"

   DO P&routine.        && P1 can be in an overlay.
