The information in this article applies to:

Microsoft NMAKE Utility for MS-DOS, versions 1.01, 1.1, 1.11, 1.12, 1.13, 1.2, 1.3, and 1.4
Microsoft NMAKE Utility for OS/2, versions 1.11, 1.12, 1.13, 1.21
Microsoft NMAKE Utility for Windows NT, versions 1.4 and 1.5

You can access environment variables within a MAKE or NMAKE makefile in the same way that you access user-defined macros. The only difference is that the names of environment variables must be capitalized when used in this manner. For example:

# the INCLUDE "macro" will pick up your INCLUDE environment variable

file.obj : file.c $(INCLUDE)\file.h

    cl /c /Zi /Od file.c
