>My question is:
>1) When I convert field type or insert fields in the mid of a table, are they actually/ physically being appended at the end of the table?(with the original one deleted), this will make sense if VFP then records their intended logical position in the DBC that holds the table.

It depends on what did you use. If you used ALTER TABLE command, then new fields would be the last. If you used MODIFY STRUCTURE command, then the fields would be where you placed them.

>2) When I double-clicked a DBF file from Window Explorer to browse it in a copy of VFP lanuched, what command is actually issued to browse the table?

It is possible that it uses BROWSE LAST command instead of BROWSE NORMAL. If it uses BROWSE LAST, then you can not trust the sequence of fields.

You can always verify your fields using

AFIELDS(laFields)

display memory like laFields
