Isn't the best solution is to convert the CSV to something
else? Maybe Maptitude could have a converter to say a dbf and then to is moved
into Maptitude.

Subject: RE: [Maptitude] Re: Read-Only Columns
I'm sorry I didn't realize that there is one file type where this problem
happens! I use CSV files so rarely myself that I didn't think of them.
Unfortunately, CSV files are read-only for most purposes.
The reason is that if you were to change a value in one cell, the entire
table from that point on would have to have to be rewritten. This is
different from other formats (dBase, Fixed format binary, Fixed format
ASCII), which have the room in the file.
I'm in complete agreement with you that it is a awkward that Maptitude
allows you to add a column to the file, but not to modify it. I'll make
sure this gets passed on to the right people. If nothing else, the user
should be warned that adding a column to a CSV file will result in an
un-editable column.

Subject: [Maptitude] Re: Read-Only Columns
I created a point file from a .csv file. Opened it for exclusive
access, but when I added a column from the modify table/add field it
was read-only. There were no instructions given by me to make
anything read-only: Maptitude decided that on its own. The only fix
was to rebuild the file. I can't figure out why anyone would want to
add a column to a table and not be able to update it.
