Using an NMAKE Macro
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at Using an NMAKE Macro.
To use a macro, enclose its name in parentheses preceded by a dollar sign ($) as follows.
Syntax
$(macroname)
Remarks
No spaces are allowed. The parentheses are optional if macroname is a single character. The definition string replaces $(macroname); an undefined macro is replaced by a null string.
