In typical statistical operations (like LINREG and FACTA) the maximum
number of variables in SURVO 84C was at most 90.
In SURVO MM greatest permitted dimensions are much higher but depend
on the size of the central memory. In 128MB no substantial limits
will be encountered. For example, factor analysis can be made even
with 1000 variables.
