Press F11 to show (toggle) the Paper Roll & Register Window,
or select it from the Window menu.
Paper Roll Window
In algebraic input modes, the "paper roll" keeps a historical record of your calculations. It is updated
each time you press [ENTER], and the history is maintained between application starts.
The paper roll text is also editable, so that you may add your own annotations. It will not keep an indefinite
record, however. Eventually the oldest entries will be deleted to make room for new ones,
and any notes added will be lost also.
In Reverse Polish Notiation input mode, the RPN stack is shown in place of a paper roll. The stack size
is configurable from the Options Window. In this mode, the RPN stack is not editable.
The "Memory Registers" page tab allows you to view and edit any numeric value held in DreamCalc memory.
See below, right.
Values can be stored and recalled from the calculator keypad using [STO] and [RCL]
with keys marked "MEM", "A"-"F" and "0"-"9". Any change to a memory value will be shown in the window instantly.
Example 1:Store and Recall
345 [STO] [A](store to 'A' register)[AC](all clear)212 [+] [RCL] [A](recall from 'A' register)[ENTER]
Displays: 557 (result of 212 + 345)
Example 2:The MEM Register
10 [STO] [MEM](store to 'MEM' register)5 [SHIFT] [M+](add to 'MEM')3 [SHIFT] [M-](subract from 'MEM')[AC](all clear)[RCL] [MEM](recall sum)
The additional registers "rx" and "ty" are used with the P►R and R►P functions to access result values.
