The ENT and COMP symbols
Listed fi nancial variables are categorized by whether they are
known or unknown. When the variable is selected (displayed),
the "ENT" and/or "COMP" symbols will appear to indicate that
the current variable may be entered (known variable) and/or
calculated (unknown variable), respectively. For details, refer to
the explanations or examples for each fi nancial function.
Note: TVM variables (N, I/Y, PV, PMT and FV) can be entered
(known variables) and calculated (unknown variables),
however, neither "ENT" nor "COMP" will appear on the
display.
