Here the -destring- makes life more difficult!
Given the original string variable
forval i = 1/13 {
gen q`i' = real(substr(mystr, `i', 1))
}
when there are 13 characters.
Sophie needs to tell us how incomplete strings (<13 characters) are to
be interpreted. How do you know which questions were answered?
There was discussion in
SJ-3-1 pr0008 Speaking Stata: On structure & shape: the case of mult. resp.
. . . . . . . . . . . . . . . . . . . . . . . . N. J. Cox & U. Kohler
