Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

    32,767 characters.
 
  • A BLOAD or BSAVE operation directed to a non-disk
    device.
 
  • A graphics statement in an invalid screen mode or when
    forms are showing.
 
  • A COLOR statement value that is not supported by the
    current screen mode.
 
  • A LOCATE statement value of 0 or a value greater than
    the available number of rows or columns.
 
  • A SCREEN statement value that is not supported by
    your video adapter.
 
  • An ISAM BEGINTRANS statement with a transaction already
    pending.
 
  • An ISAM COMMITTRANS statement without a transaction
    pending.
 
  • An ISAM ROLLBACK statement that refers to a savepoint that
    does not exist, or a ROLLBACK ALL statement with no
    transaction pending.
