HP 48g Graphing Calculator - Manual (Page 80)

Input forms use four basic kinds of fields:
■ Data fields. These accept data of a particular kind directly from the
keyboard. The fields labeled INDEP:, H-VIEWs, and V-VIEW in
the PLOT form are examples of data fields.
■ Extended data fields. These fields extend the abilities of data fields
by also allowing you to enter an object you have previously stored
(as long as it is an allowable type for that field). The EQ» field in
the PLOT form is an example of an extended data field.
■ List fields. These fields have a limited, pre-determined set of possible
values, of which you must choose one. The TYF’EI” and fields in
the PLOT form are examples of list fields.
■ Check fields. These fields control various options in the applications
(a check in the field makes the option active). The flUTOSCHLE field
in the PLOT form is an example of a check field.
