About Help Browser

If you want to write your own help file it is strongly recommended to take this help file as starting point and follow the structure of the HTML. Then check the appearance in calculator browser, whether it looks as expected.

See "Special characters available" for list of supported characters in help file.

A STO represents a physical button

Stack

Stack consists of 10 registers. All arithmetic operations use for arguments and results top level of the stack as is usual for RPN machines.
Stack registers could be also accessed using RCL and STO with negative indexes -1 to -9.

Example of stack display:
6: 0
5: 0
4: 0
3: 0
2: 321232.123ᴇ-12
1: 54.344234342
0: 123.32

Registers

Register area consist of 100 registers. Registers could be accessed using RCL and STO with indexes 0 to 99.
