There are multiple solutions possible: 1) Making the functions public and creating the aliases as external: procedure X; public name 'X'; begin WriteLn (1); end; procedure Y; external name 'X'; begin X; Y; end. 2) Using procedural variables / constants: type TProc = procedure; procedure X; begin WriteLn (1); end; const Y: TProc = @X; begin X; Y; end. 3) Using inlining: procedure X; begin WriteLn (1); end; procedure Y; inline; begin X; end; begin X; Y; end.
