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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

The variable is not of the required type. For example, you
are trying to use the SWAP statement with a string variable
and a numeric variable, or with two numeric variables of
different types. This error also can occur when using ISAM
in these conditions:
  ■ During an OPEN FOR ISAM operation, the data type of a
    record element does not match the data type of a table
    column.
  ■ During an ISAM INSERT operation, the number of elements
    in the record does not match the number of columns in
    the table, or the data type of a record element does not
    match the data type of a table column.
  ■ During an ISAM RETRIEVE operation, the data type of a
    record element does not match the data type of a table
    column.
  ■ In an ISAM SEEKoperand statement, there is a data-type
    mismatch between the key-value argument and the current
    index.
  ■ During an ISAM UPDATE operation, the record variable is
    not the same user-defined type as the table you are
    attempting to update.
