Just a stab ... this is pseudocode you would have to look up the syntax:

Select *, ;
(value) as < < new field name > >, ;
(value) as < < new field name 2 > > ;
from oldtable ;
into table newtable

close data all
rename oldtable to < < backup name > > && you can never be too safe
rename newtable to oldtable
use newtable (using oldtable name) in select(0)
index on ... tag ... , etc.

In the above, the values in the select statement should be the correct type and picture for the new fields:
0000000.00 for a numeric -- just adjust the value to the size you want,
space(10) for a character -- adjust the number of spaces for the size
.t. for a logical, etc.
