Notice that, with the exception of fields with decimal points,
you cannot visually determine the type of data that a field will
accept or display. If the label associated with a field does not
clearly define the type of data that you can enter in the field,
ask your data administrator for this information. The
application will not allow you to enter data of an invalid type
in a screen field.

identify the number of characters (letters or digits) that a
field will accept by examining the dashed lines that make up the
field. Suppose, for example, that a field appears as follows:
