[Limdep Nlogit List] variable types

Dear Charles:  The order in which variables appear in the data editor does
not have any meaning in any context.  For example, if you have variables
x1, x2, x3, x4, the construction x1 - x4 does not have meaning.  As such,
there is means provided to reorder variables because the order already
has no context.  For the categorical variable, you have the right syntax.
problem is that the variable hlthsat has some miscoded noninteger values
(between 6 and 7).  If you use CREATE;NewHSAT=Int(hlthsat)$ you should
be able to make the conversion. As for the type of variable, this
is not stored with the variable, but you can obtain it by using
DSTAT;Rhs=the variable(s) ; Values $
This will give you some information about the variable, and show you what
is wrong with HLTHSAT.  (This is in Section E2.6.3 in the manual.)
