being considered consistent.
ACTION There may be little that can be done in this case. Call HP for
assistance in piecing together your form file. It is helpful
to know what changes were made since the last time the form
file was consistent.
------------------------------------------------------------------------------------
286 MESSAGE Error when writing to form. Form possibly not displayed
correctly.
CAUSE After displaying a form, BASIC does a cursor position check to
see if the cursor is where it should be after display of the
form. If it is not in the expected position then this error
occurs.
ACTION There are several reasons for this problem, such as a corrupted
form or a terminal that does not have enough memory to display
the form.
------------------------------------------------------------------------------------
287 MESSAGE No input fields in form.
CAUSE The program has tried to read data from a form, but there are
no input fields on that form.
ACTION The form must have an input field for input to occur.
------------------------------------------------------------------------------------
288 MESSAGE No output fields in form.
CAUSE The program has tried to write data to a form, but there are no
output fields on that form.
ACTION For output to occur while a form is active, there must be an
output field in the form. The exception to this is the LDISP
statement. See the JOINFORM appendix for an explanation of how
LDISP works when a JOINFORM form is active.
------------------------------------------------------------------------------------
289 MESSAGE Output too long for output field {field_number}.
CAUSE This indicates that an output statement has tried to display a
value which is too long to fit in the current output field of
the active JOINFORM form.
ACTION The field must be made larger or the data smaller. The largest
field size is 80 characters.
------------------------------------------------------------------------------------
291 MESSAGE Illegal operation inside form.
CAUSE The LENTER statement cannot be executed when the cursor is
located within the currently-active JOINFORM form.
ACTION Before executing the LENTER statement, use the CURSOR statement
to position the cursor to a location outside of the form.
------------------------------------------------------------------------------------
292 MESSAGE Attempt to read past last input field of form.
CAUSE The input field pointer is undefined because all the fields on
the form have already been read.
ACTION Use the CURSOR IFLD(input_field_number) statement to position
the input field pointer to the desired field.
------------------------------------------------------------------------------------
293 MESSAGE Attempt to write past last output field of form.
