Ok, so -encode-ing will be mandatory for Maryle now...

Well, -tsspell- (SSC, Cox) is an improved version of -spell- (SSC, Cox and Goldstein). The older program did not make use of time series notions, and you could get away without -tsset- in using that tool (as -help tsspell- indicates). But the -ts- operators bring so much useful housekeeping details that it seems silly to avoid taking advantage of them. In that respect creating a numeric 'i' variable (via -encode-) that allows you to -tsset- or -xtset- the data is a minor inconvenience.
