If we create a macro variable in side a data step .Is it work any other data step or work like global or local variable.
Thanks and Regards,

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
--*;
