you can create using proc sql and also when you create a macro program parameters are automatically macro variables.

Hi...

we can create macro variables in many ways.

1. %let
2. call symput
3. into(proc sql)
4. macro(while passing parameters into the macro ,that parameters are acts  as local macro variables)

and if you use %do statements in with in the macro,

for example %macro test;

                   %do i=1 %to 10;

                     ..........

                     ...........

                    %end;

in that example "i" also become a local macro variable.

and I don't think that  we can create macro variables directly by using %local and %global statements.

generally we use % local and %global statement before %let statement to specify weather the macro variable become local or global.

That's not entirely correct. %local and %global create macro variables with null values. Even without assigning a value to them with %let, you can reference them without error.
