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.
