Thanks guys for your replys,, for a moment I thought I saw a posting
in wich you can actually do the Modi Struc for a View cursor,,
but I think is different.
What I wanted to do is,that usually I work with large tables for diff
projects and certain fields (not all the fields) for example,
name, address , city state zip dpb fields need to be formated in a specific
format for BuscroEktajet machines for Bulk Mail processing and I tough
if I created a cursor with the req fields and then add some temp ones
then most of the formating routines will run wayyy faster in memory rather
than I/O process in the original table.
that's all, some of my tables are about 1.5M records and 500,00 recds

thanks
Mark

>>>Any time you SELECT...INTO CURSOR, the resulting cursor is read-only, no matter what you do before hand. You can fake it out by USE DBF('thatcursor') ALIAS rwcursor into making a R/W cursor. Your SELECT statement must not be a "filtered-view" so use the NOFILTER clause in your SELECT.
