Warning: this record has xx fields instead of yy

The number of fields in this record in the data file did not match forms-number-of-fields. Missing fields will be made empty.

Multi-line fields in this record - update refused!

The current record contains newline characters, hence can not be written back to the data file, for it would corrupt it. Probably you inserted a newline in a field, while forms-multi-line was nil.

Field separator occurs in record - update refused!

The current record contains the field separator string inside one of the fields. It can not be written back to the data file, for it would corrupt it. Probably you inserted the field separator string in a field.

Record number xx out of range 1..yy

A jump was made to non-existing record xx. yy denotes the number of records in the file.

Stuck at record xx

An internal error prevented a specific record from being retrieved.

No write access to "file"

An attempt was made to enable edit mode on a file that has been write protected.

Search failed: regexp

The regexp could not be found in the data file. Forward searching is done from the current location until the end of the file, then retrying from the beginning of the file until the current location. Backward searching is done from the current location until the beginning of the file, then retrying from the end of the file until the current location.

Wrapped

A search completed successfully after wrapping around.

Warning: number of records changed to nn

Forms mode’s idea of the number of records has been adjusted to the number of records actually present in the data file.
