ead=cats('z',level_1,level_2,level_4,level_6);
what does this do?
Please consult the documentation: CATS Function and come back if details are unclear to you.
It concatenates the string 'z' with the strings listed in the columns that are specified as arguments. It removes leading and trailing blanks before concatenation, I think.
The CATX function will also remove leading and trailing blanks. The CAT function keeps them.

Since it is not part of a data step or other procedure that allows such code it does nothing and probably throws an error.

Have you tried placing the cursor in the SAS editor on the function, such as CATS, and pressing F1? Does anything happen?
