Answer is B.
ReplyDeletedata monthly (keep = sales);
do i = 1 to 60;
sales = i*10;
output;
end;
run;
data work.totalsales(keep = msales{12} ) ;
set work.monthly (keep = sales);
array msales {12} ;
do i=1 to 12;
msales{i} = sales;
end;
run;
log file:
153 data work.totalsales(keep = msales{12} ) ;

Program will run without errors if we change keep = statement as
data work.totalsales(keep = msales1-msales12 ) ;
set work.monthly (keep = sales);
array msales {12} ;
do i=1 to 12;
msales{i} = sales;
end;
run;
syntax error - coz there is no variable as monthsale{12}...the variable is monthsale12

ReplyDeletethe answer is b syntax errror.
ReplyDeletewe can't use array variables in the keep/drop options because array variables are temporary and available only at the time of execution. we have to mention the name of the variables created by array if required in the keep option.

Good luck!
How about (keep=months ales)?
ReplyDeleteWhat is the difference between Data error and Syntax error?
ReplyDeleteI agree that the array causes and error, but this seems like a data error to me, not a syntax error! Can anyone elaborate?
ReplyDelete(Keep=monthsales1-monthsales12) will work.
ReplyDeletewe have to mention the name of the variables created by array if required in the keep option.
