Hi!
In TBROWSE.PRG, there's a HIDDEN property named
::lNewRow for TDataCache() class. IMHO, it must be
removed:
1) ::lNewRow uses EOF() function to work. TBrowse
shall not be aware about any kind of data
source.
2) Since EOF() doesn't have any alias assignment,
it would produce wrong results (sample included).
3) An "append mode" record should be managed by
user's code.
Can I remove it?
Atte.
