In the input screen there is often information about the pro-
blem you are going to solve (formulaes etc). Remember the
' ' in algebraics and separation of several data on the same
input line by using blanks (space).
Echoing from the stack
If an expression or a value laying on the stack is going to be
used, then the EDrT/tSTK/ECHO/ENTER sequence will
load data into the input screen. Be sure to place the cursor
When a calculation is finished CALCULUS will either show
up intermediate results by using the VIEW routine (intrinsic
MAII) or return directly to the menu. In the last case you will
need to use the ->STKkey to see the result laying on the stack.
Moving up and down in the menu
You can move downwards in the menu system by scrolling
the dark bar and pressing ENTER. If you need to move up-
wards the UPDIR key will help. At any time you may HALT
CALCULUS and use the calculator independent of CAL-
CULUS by pressing the -^STK key. CONT will get you back
to the menu system.
