This is a data calculator that does computations with arrays of numbers
(data vectors). Each data vector consists of a pair of arrays X and Y. Most
calculations are performed on the Y array. Twenty X-Y data vectors
are available for storage (0...19). For each operation, the data
vectors are dynamically identified (via a selection list) as S, T or U data vectors.
The parts of the calculator are:
- Lets you know if the calculator is BUSY or READY and displays
information about computational operations when the INFO buttons are pressed
or a new computing option is selected. Do not attempt
new calulations while the calculator is busy.
- DATA ENTRY (DE)
- Used for data entry (via typing or
cut-and-paste) and for data display.
- A, B, C
- These are registers that are used for
input of computation and information processing parameters.
- S, T, U
- These are selection lists that identify
a letter (S, T, U) with a specific data array number
(0...19). Nearly all computations use these vectors and
users must be careful to manage array usage to retrieve and store
results in the available arrays.
Each data vector consists of a pair of arrays labeled X and Y.
- INFO, RUN Process and Function option lists
show the computing and processing options of the calculator.
INFO displays information about the currently selected option in the
STATUS window. RUN does the computation.
- EraseDE, EraseSL, RESET
- These buttons erase the DE,
SL text boxes or reset the state of the calulator.
- DEGREES, COLUMN
- These are options to set if (1) calculations are to be
done with degrees or radians or (2) X-Y data is to be
displayed in columns or single row format.
- SESSION LOG (SL)
- Displays a log of user activity and displays
some of the results of calculations (STATS, LINEAR
