I've never used SAS but I have used Stata [NB].

But the message does explain the problem, which may be why no-one
answered this first time this was asked.

At least one of your variables -v y u t a b- contains something other
than integers. So,

. codebook v y u t a b

to see which variable(s) don't come up to scratch. Perhaps one is
string. Even if SAS permits string predictors (I don't know its
terminology), Stata expects you to -encode- string variables before
using them in -anova-.

(Please note our policy on repeating posts. It's best to wonder why a
post didn't get answered, and revise it, and not to seem too
impatient.)
