using call excute

by using symput command

Using & (Ampersand)

We can call the macro with CALLSYMPUT

Use callsymput in data step.
EX:
 
Data _null_;
set group;
call symput('_grpname',group name);
run;

using  symget

data one;
symget &macro1;
run;

We can call macro in a dataset by preceding % with macro 
name.

call symput - used to create macro variable in data step.

symget - used to assign value of macro variable to data 
step variable.

oh....use less felows don't give this much answers how can 
a person knows which one is the correct answer,i can see 
here more wrong answers than correct answers.i suggest some 
of the people who don't know the exact answer better don't 
post stupid answers ,why because the persons who are facing 
the interview they are in learning stage they can't 
differentiate the answers.

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

%include statement can be used to call a macro within a 
data setp.

or 

call a macro with %macro-name (only if the) in the datasetp
(condition that this marco exists in the central location 
where it is defiened).

Please anybody suggest if these are right answers.
