Calcnote is a short note program for the TI-83Plus. This is not a program written in response to all the bad and useless "String manager" programs, though there are quite a few. Calcnote saves five separate messages of up to 153 characters each in specially formatted Str9 (a concept I call a "Virtual string", but referred to in this document as a note). Unless you hit one of the two known errors (which I am working on), or hit the [On] button, you might not guess that this is a program written in TI-Basic. This is my goal; A program that will not ask the user to do anything extra, and proforms it's task in a clean way. By clean, I mean both a good interface and as little impact on the rest of the calculator as possible.
Now if anyone would try to make an assembly program based on this interface, I would not object. . .
Beginning navigation is simple. There are four options in the beginning menu; Edit a note, Look at a note, Delete a note, and Quit Calcnote. To move between these options, use the up and down directional (arrow) keys, and press [Enter] to select. The next menu that comes up, if one of the first three options is selected, is a note selection menu. If there is an error at this point, select exit and see "String Format" in this document. Navigation is still by the directional keys, selection by the [Enter] key.
If you first selected "Edit", you will get a cleared area to type in. See "Available Keys" for the characters available, and also for error within this part of the program. When you are done, save and quit by pressing [Enter]. If you selected "View", you will see an un-editable view of the note selected. Hit [Enter] when you are done. If you selected "Delete", you will be prompted to press [Clear] to confirm. If any other key is pressed, the note will not be deleted.
From here, Calcnote will store your string and clean up after itself. The program is then done.
Five strings can be stored at a time. If Str9 is not in a certain format, the program is likely to error. To get a correctly formatted string, go to the Home screen and type in the following (include quotation marks):
"Str1 Str2 Str3 Str4 Str5 Str6"[STO]Str9
Messages are stored in the spots taken by spaces. For example, if the message in note #3 was "Calcnote is Great", with no other notes, Str9 would look like this:
"Str1 Str2 Str3CALCNOTE IS GREATStr4 Str5 Str6"
"Str6" is simply a end marker.
In edit mode, there are two available keyboard sets, the first by default, the second by pressing [Alpha]:
|
|
Standard Keys available |
Keys available in Alpha mode |
If one of these keys is not pressed, an error will occur. to recover you work, select quit and type in:
Str6+Str7+Str8->Str9
Then restart the program.
There is one major limit I have not mentioned; the maximum note length is 153 characters, imposed by the current display engine limitations. If you try and pass this limit in Edit mode, you will get a message of "MAXIMUM LENGTH REACHED". Calcnote will pause instead of error because of this safety feature. When [Enter] is pressed, Calcnote will save a safe version (153 characters) of the string and exit.
