Anyone know of a function that can be used to return variable type? For example, I'd like to get a return value on a variable and, if it is numeric, convert it to string. Something like "vartype" the following pseudocode:

variables: major1 (string), major2 (string), major3 (numeric, since it happens to be empty this year)

foreach x in major1 major2 major3 {;
if vartype(`x') is numeric {;
	gen temp=string(`x');
	drop `x';
	rename temp `x';

Any thoughts?
