If these macro variable are maked at Open code, they are all global macro variables ,you can use them at anywhere  . But if they are maked inside a macro and you don't define them with %global, then they only can be used in this macro(i.e. local macro).

You can create both local and global variables by running a data step. If you are using CALL SYMPUT, then there are some complicated exceptions. I tend to use CALL SYMPUTX with the third argument, to show my intention a little bit more clearly:

  %macro mymacro();
    %local local;
    data _null_;
      call symputx('local', 'local', 'local');
      call symputx('global', 'global', 'global');
    run;
    %put _user_;
  %mend mymacro;
  %mymacro()
  %*-- on log
  MYMACRO LOCAL local
  GLOBAL GLOBAL global
  --*;
