Use -ds- to condition on the type. See

Listers,

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?

Best,

Bryce
