Array Subset Out Of Range - n00b

[jdgriffin]

 First time posting on the discussion boards here (I believe). 

I continue to encounter the error: "ERROR: Array subscript out of range at line 61 column 31."

The code is as follows:

data conversion;
set work.combo2;
array original_variables{7} rawsug refsug HFCS glucose dextrose total totalsweet;
array conversion_variables{7} rawsug_tbsp refsug_tbsp HFCS_tbsp glucose_tbsp dextrose_tbsp total_tbsp totalsweet_tbsp;
do vars= 1-7;
	conversion_variables{vars} = original_variables{vars}/3; /* This is line 61*/
end;
drop vars;
run;

And the exact error message:

ERROR: Array subscript out of range at line 61 column 31.
 Year=1970 Grains=6.93 Dairy=1.81 Meat_Fish=3.25 Vegetables=3.29 Fruits=1.12 Uspop=205.052 RawSug=37.112167365 RefSug=34.684268565

 vars=-6 _ERROR_=1 _N_=1

 

I'm using an example from Section 13.5 "Learning SAS By Example" as my template and it seems like this should work. is there something I am missing?

Thanks for taking the time to review.

Looking at the error you can see VARS=-6

Your do statement is incorrect and resolves to

do vars=1-7 -> do vars=-6

You want

do vars=1 to 7;

Thank you for the quick reply. It is much appreciated. 

EDIT: That fix worked perfectly!
