Flags

Through the MODES MISC menu:

Beep
Undo stack
Arguments

Through the MATH BASE menu:

Through the MODES FMT menu:

Through the MODES ANGL menu:

DEG
RAD
GRAD

Through the TIME menu:

Simple algebraical expressions examples

'B*H/2'
'(π*R)^2'
'25*((3+9)/3)'

(Use EVAL command to evalutate the expression)

Simple programs examples

<< B H * 2 / >>
<< π R * 2 ^ >>
<< 3 9 + 3 / 25 * >>
<< -> C1 C2 << C1 SQ C2 SQ + e >> >>
<< -> C1 C2 'SQR(C1^2+C2^2)' EVAL >>
<< -> B H << B H * 2 / >> >>
<< -> B H 'B*H/2' EVAL >>

Note that each item in a program must be separated by space

Limitations

Maximum input length for any type of data : 254 charactes
Maximum memory for data: 9216 bytes

(Use the MEM command to check the amount of free memory)

Extra features

FMOON & NMOON options in library menu. This two options calculate aproximately the full moon and new moon date in a month for a specific date in stack 1. (Use the DATE command to generate a valid date)
EASTER option in library menu. Calculates the easter date for a specific year in stack 1.
