In NMAKE, the backslash "\" character has two different meaningsdepending on the context in which it is used. It can be used as a line-continuation character or as a path specifier.
The backslash is used primarily as a line-continuation character. Forexample, if a dependency line in your makefile extends to more thanone line, use the backslash to continue it to the next line. You canplace a space prior to the backslash or append it directly to the lastdependent file, as the following examples demonstrate:
TARGET1: obj1 obj2 obj3 obj4 obj5 \ obj6 obj7
TARGET2: obj1 obj2 obj3 obj4 obj5\ obj6 obj7
NMAKE also uses the backslash as a path specifier. When a backslash isthe last character on a line and is used as a path specifier, place acaret "^" character before the backslash to override its default useas a line-continuation character.
The following macro definition demonstrates using the backslash as apath specifier.
exe_dir = c:\bin^\
In the following case, NMAKE interprets the trailing backslash as aline-continuation character which is contrary to the meaning thecontext requires:
exe_dir = c:\bin\
In a macro, specifying two backslashes in succession ("\\") nullifiesits use as a line-continuation character. However, when NMAKE expandsthe macro, both backslash characters appear and an incorrect pathresults.
