If you know the path of the macro file you can use %include statement.
If the macro is stored compiled macro, you can use mstored and
sasmstore option. For example,
libname maclib 'c:/cmacros' ; *Assign library to the location where
compiled macros are stored;
options mstored sasmstore=maclib; *This option statement tells maclib
is the library for stores compiled macros.
%callyourmacro; *This is to invoke your macro.
I din't undesrand wht you mean by "without vieving the content of the
macro". I always suggest you to view/go through the contents, it helps
you to understand the source code of the macro, how to invoke it, what
are the default argument values etc.
