data temp;

set temp1;

y=5;

y = y + &x.;

run;

%mend;

You may be looking for SYMGET as well if the application is more complex then your example.

Yes. For every observation read from TEMP1 and written to TEMP will have Y=10.

You can try it without the macro wrapper by just using %LET to set the value of the macro variable X.

%let x=5;

data temp;

set sashelp.class ;

y=5 + &x ;

put (name y) (=);

run;

Name=Alfred y=10

Name=Alice y=10

Name=Barbara y=10

Name=Carol y=10

Name=Henry y=10

Name=James y=10

Name=Jane y=10

Name=Janet y=10

Name=Jeffrey y=10

Name=John y=10

Name=Joyce y=10

Name=Judy y=10

Name=Louise y=10

Name=Mary y=10

Name=Philip y=10

Name=Robert y=10

Name=Ronald y=10

Name=Thomas y=10

Name=William y=10
