-tostring- can figure out the strings itself, though.

set obs 1
gen str3 major1="yes"

foreach v of local varlist {

action for string variables

else {
action for numeric variables

...
for your case you could do something like:
foreach v of varlist major1-major3 {
capture confirm numeric variable `v'
if !_rc {
tostring `v', force replace
}
}
Also, you could use -ds- to make a varlist of string or numeric vars to
manipulate. (-help ds-)
