RE: Updating Records

["Bob Cozzi" <cozzi@xxxxxxxxx>]

I would not recommend this approach. Use the File Additional option ("A" in
column 20 on the F spec as others have suggested. This declares the file for
Input and Output (but not update).

I am not quite sure I understand what you mean by override?

Blast it!  ignore my previous msg --  use this one:
Declare it for update, with additions, i.e:

    FFilename  UF A E           K Disk

This way, you can read and/or write.  The other way would be to declare
the same file twice, with different names:

    FFilename  IF   E           K Disk
    FFile2     O    E           K Disk    ExtFile('LIB/FILENAME')
    F                                     Rename(FmtName:FmtName2)

This way, you can use Filename to input, and File2 to output to.  The
system should use blocking this way, so it might be faster.  When
compiling this second method, you must override the FILE2 entry to point
at FILENAME, ie.

OVRDBF FILE2 TOFILE(LIB/FILENAME)

Hope this helps
