I have a string variable with a list of variable names. How can I tell if those variables are empty
or not? I couldn't find any combination of eval/empty code that would let me do this...
Ex:
The variable rq is set to "field1,field2,field3". I want code to determine whether field1,
field2, or field3 are empty.
