- DEFINITION MODULE Linker ;
- (* Linker and .COM writer.
- The compiler already emits a whole image - the runtime at offset 0, the
- program after it - so there is nothing to relocate. "Linking" means
- padding the file so the program's data area exists, and writing it as a
- DOS .COM, which loads at CS:0100. *)
- FROM SYSTEM IMPORT BYTE ;
- PROCEDURE LinkSize () : CARDINAL ;
- (* Size the .COM must be: the image padded out to cover the whole data area.
- Usually larger than Compiler.ImageBytes, because the data base is a fixed
- 4 KiB above the code. *)
- PROCEDURE WriteCom (path : ARRAY OF CHAR) : BOOLEAN ;
- (* Write the linked image to `path`. FALSE on failure, and the partial file
- is removed so it cannot be mistaken for a good one. *)
- END Linker.
