CalcTool comprises of the following functions, which can be called from
the Psion calulator by using the "Load OPL" option from the Special menu
(Psion-O). Select Calctool, and the functions can be used by typing the
relevant function name. (NB - Remember to insert a colon before the
opening bracket). Programmers may also use the functions in software by
using the LOADM command within the software. Note that if you do so, the
arguments passed to the functions and the result returned, must be
floating-point. For example, Fact:(t%) will produce a type violation. This
can be overcome by using the FLT and INT functions - refer to the programming
manual for further information.

hcf:(x,y) - Highest Common Factor
lcm:(a,b) - Lowest Common Multiple
mod:(a,b) - a reduced modulus b
Fact:(n)  - n! (n factorial)
nCr:(n,r) - n Combination r
nPr:(n,r) - n Permutation r
Fib:(n)   - nth number in Fibonacci series (0,1,1,2,3,5,8...)
ClearMem: - Resets all memories to zero
TimeNow:  - Time in seconds since 00:00 1/1/70

SecsTill:(Year,Month,Day,Hour,Minute,Second) - Seconds until specified time
DaysTill:(Year,Month,Day)                    - Days until specified date
Speed:(Miles,Yards,Hours,Minutes,Seconds)    - Speed calculation.

AND:(x,y) - Logical AND function
OR:(x,y)  - Logical OR function
NOT:(x)   - Logical NOT function
XOR:(x,y) - Logical XOR function

NB These Logical function give the result that would be obtained if the
arguments were converted to binary - eg AND:(10,7) = 1010 AND 0111 = 0010 = 2
