Here is an example. - tostring major3, replace- is much faster, though...
*******
clear*
set obs 1
gen str3 major1="yes"
gen str2 major2="no"
gen major3=3
qui ds, not(type string)
foreach x in `r(varlist)'{
gen temp=string(`x')
drop `x'
rename temp `x'
}

Subject: st: Testing for variable type
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
