st: Re: scrolling over observations

["Michael Blasnik" <michael.blasnik@verizon.net>]

The error from encode indicates that your company name variable was actually 
numeric to start with (I assume it was just some numeric code of some type 
but not already encoded?).  In that case, encode certainly wouldn't work and 
the other solutions make sense.
