Error: "in list does not match type prescribed for this list" using PROC UNIVARIATE

[_maldini_]

I am using SAS University Edition.

I am receiving this error while using the PROC UNIVARIATE procedure. Other posts on this forum, and on other sites, refer to this error in the context of importing data. There is a suggestion that this error results when the data types are different. Both of these variables are numeric.

The procedure runs without error when only 1 variable is in the VAR statement.

Code: 

PROC UNIVARIATE;

VAR var1 var2;
RUN;

Error: 

ERROR: Variable var1 in list does not match type prescribed for this list.

ERROR: Variable var2 in list does not match type prescribed for this list.

Thanks for your assistance.

Proc univariate requires numeric variables. Run a proc contents on your dataset to see your variable types. You don't have a DATA= portion in your proc? It's not required, but I'd highly insist on it, so you can trace your code. 

proc contents data=have;
run;

proc univariate data=have;
var var1 var2;
run;

Thanks for the assistance.

Somehow these variable have been "typed" as character data. Yikes. I'm not sure how this happened.

Any suggestions for changing the type?

Btw, I will heed your recommendation on specifying the dataset.
