; This file demonstrates an alternative set of methods for building
; projects using MASM. The project should be built using MAKEIT.BAT
; It will not build in the MASM32 environment as it uses a different
; technique.

; The method is to set the environment variables of BIN, INCLUDE and
; LIB in the batch file, build response files for both ML.EXE and
; LINK.EXE to handle multiple modules. The resource file is directly
; handled by LINK.EXE which calls CVTRES.EXE to manage the resource
; conversion. The techniques involved are the basis of much larger
; architecture dealing with multimodule projects that are worked on
; by a team of programmers.

; Response files are designed to overcome the command line length limit
; when using a large number of modules by creating a file in the format
; that both ML and LINK are designed to handle.

; In this simple example, parts of the normal file have been made into
; seperate modules that are built using this method. The module format
; is the same as the MASM library format which is another method of
; dealing with very large projects written by a number of programmers
; in a team.

; The methods used are written into the MAKEIT.BAT file and would be
; equivalent to a BUILD ALL command for the project.
