The VFP low level file functions (LLFF) can be used to open a table as a file and read/write its header. The Table Header Record Structure is documented in VFP help under Table File Structure.

Note 1 Removing Structural CDX flag will effectively disassociate CDX file from the table but not delete the CDX file.

Note 2 Removing Memo flag will allow to open a table and access all fields excluding memo fields. Attempt to access the memo fields will generate an error.
