WP-34S newbie user - but how to start?

With indirect addressing I want to select a variable not a program label:

An example:
If I have an equation to calculate area (A) of a circle from its diameter (D), I can use the following program with indirect addressing (A=D^2×PI÷4):

Code:


Variables:
----------
  R00: for indirect addressing,
  R01: D (diameter of circle in meter),
  R02: A (area of the circle in sq. meters)

Program:
--------
  LBL'CIR'
    STO->00
    RCL 01
    x^2
    PI
    ×
    4
    ÷
    RCL-02
  RTN
  END

Examples:
---------
A.) Calculating area from diameter: D:=2m -> A=3.14m^2
2 STO 00     // solve the equation for A
STO 01
f SLV 'CIR'
on the stack you can see the result: 3.14

B.) Calculating diameter from area: A:=150m^2 -> D=13.82m
1 STO 00     // solve the equation for D 
150 STO 02
f SLV 'CIR'
on the stack you can see the result: 13.82

Quote:Try the DATE or TIME commands

In the firmware identifier I found a "T" and I got a good hint in PM (thanks again): the XTAL? command gives me "true", so I guess I have a crystal!

Thanks for the answers!
