1 CALCULATOR 
The CALCULATOR program is an emulation of a Hewlett-Packard reverse polish
calculator. It is for VT200, VT100 and VT52 video terminals only.  Help is
available by entering a '?' or by pressing the key sequence GOLD/PF3 after
invoking CALCULATOR. 

To invoke CALCULATOR, simply type CALC at the '$' prompt. The command to
invoke the old system calculator program has been renamed to OLDCALC.
