Answer / learner
We have to use call execute to call a macro. For other
answers
1 &(amperson) is used to resolve the macrovariable and not
call macro .
2 Call symput is to define a macro variable dynamical in
data step. useful in data driven programs.
3 symget is to get the macro variable from symbol table and
not call a macro.
Hope it will help..would recomand to double check before
post ..al the best

step variable.

Answer / net_ameen
Call Execute() is used to call Macro aswellas call macro variable eg: Call execute ('%macroname');
Call execute ('¯ovarname');
Call Symput() is used to create a Global macro variable from within a datastep.
Symget() is used to call a macro variable and assign its value to a datastep variable.
%include() is not a macro statement yet used to call either a macro, extn file containing codes or proc/datastep within a program to be executed together.
Resolve() is used to resolve macro variables created thru call symput within same datastep.
Hope this helps. If any argument pls post.
