The m03 Software Arithmetic Program

=============================== The m03 Arithmetic Program =============================== General Description ---------------------- M03 is an application program for both software and hardware calculations on numbers. The software can figure answers up to 158 digits long. The hardware logic does various trigometric and mathematical functions. There is also a statistics option, that uses the software arithematic, to calculate means, mediums, modes and standard deviations of lists of numbers. There is a good collection of editing options for the data; various report formats can be fairly easily constructed, using interval-merge, align, and shift functions. Data can be kept, or read, thru the input and output options. For processing, m03 uses two different screens: edit and browse. This is to give a cleaner screen for viewing the data in the file area. --------------------------------------------------------- DOS Based --------- M03 is a DOS based program that runs under Windows 95/98 and can run in a MS/DOS only environment. Under Windows, it runs in a DOS window defined by a PIF [program information file]. ---------------------------------------------------------------- ..........Operating m03 ............ The Option Table ----------------- There is an options table that springs up on the lower part of m03's main screen. It appears whenever a non active key is pressed: -------------------------------------------------------------------- Input Edit Position Commas in Ans HW Arithmetic Output Intvl Mrge Even Page Insert Commas Statistics 1st Record Swap Move Lines Align On Dec Square Root Last Record Delete String Move Default Align Add Exit Move Right Lines/Screen Round Factor Subtract clip portal Move Left Info Bar Arith Sort Multiply Key Memory Search Index Nmbrs Intrvl Round Divide -------------------------------------------------------------------- MAIN SCREEN OPTIONS --------------------- Key Functions --------- --------------------------------------------------------------- arrows move screen thru data by paging or scrolling b defines 1st record of output file c defines last record of output file space turns on/off record numbers on right edge of screen m moves intervals of records to starting targets M moves lines having a given character string; can move empty lines y merges intervals of lines onto other intervals d deletes/truncates lines in an interval of lines i inputs files, changes current directory zero outputs files, changes current directory x exits m03 program e edits into a line l defines how many records will be displayed on main screen page r searches for requested character strings s swaps character strings in intervals of lines u auto aligns 1st 24 lines at preset decimal point position dot aligns on decimal points, for intervals, for requested off sets \ squares up screen on an even page boundary F12 enters Edit on previous line edited comma turns on/off commas option for answers ; inserts commas into intervals of numbers k sets round off, for number of digits to right of decimal point = turns on/off info line at bottom of screen a brings up the hardware arithmetic options list p points screen at requested line ( moves characters in lines to left ) moves characters in lines to right t opens the clipboard portal, for pasting into file area v sorts an interval of lines by their numeric values S builds a report of mean, median, mode and standard deviation R rounds off numbers in an interval, by specified amount ------------------------------------------------------------------------ ARITHMETIC OPTIONS FROM MAIN SCREEN --------------------------------------- Key Functions ------- ------------------------------------------------------------- + adds two numbers, puts answer where requested - subtracts 2nd number from 1st, puts answer where requested * multiplies two numbers, puts answer where requested / divides first number by second, for requested decimal places 2 figures square root of number, puts answer where requested S builds a report of mean, median, mode and standard deviation The first question asked is: interval? If numbers are entered, a whole interval of numbers is processed. The option is to +Arith Functions+ include running calculations - if opted, a | sin x | column figure is requested, to allow room for | cos x | the added numbers to the lines. All interval | tan x | arithmetic processing puts the answer in the | hyprblc sin x | line following the interval of lines. | hyprblc cos x | | hyprblc tan x | Non-interval arithmetic functions take 2 | arc sin x | numbers from the keyboard, operate on them, | arc cos x | then changes the screen. The next screen is | arc tan x | the browse screen, with the answer and | log x base 10 | original two numbers superimposed, in boxes. | log x base e | The program asks where to put the first two | e to x power | numbers, then asks where to put the answer. | square root x | | x to y power | An option for the answer is the 'k' key; if it +----------------+ is entered, the answer will ne entered into key memory, if there is enough room. The square root function is similar. The statistics option takes two numbers, for the interval bounds. ---------------------------------------------- Some Rounding Notes ---------------------- m03 uses an auto rounding logic for the software routines. This goes into effect if the number gets too long to fit onto one of the file lines. The program will attempt to round off the number, so that it is 158 characters long and has been rounded off to these 158 chars/digits. If it is really too long, it will be truncated, and the result will be 159 digits of incorrect answer. Auto rounding can be overridden by resetting rounding to a lesser number than 159, from the main screen, using the `k' option. Interval round overrides the round factor option and can round numbers to a different precision. ------------------------------------------------------------------- EDITING SCREEN --------------- Key Functions --------- ---------------------------------------------------------------- arrows moves pseudo cursor up, down, left, right on file lines Home moves pseudo cursor to front of line edited End moves pseudo cursor to end of line edited Insert starts insert chars mode Delete starts delete chars mode F12 exits Edit and saves edited results into line Enter puts Edit into Option mode: Key Function --- ------------------------------------------------------- m merges another line onto edited line e jumps edit to requested line; doesn't save current chgs c chops off line at point of pseudo cursor y chops off line & copies chopped off part onto next line r inserts last deleted character string k adds string from line, to key memory x exits edit mode, does not save changes l inserts line after current line Space moves line to never-never land Enter saves current line changes into line z copies line onto other line a forces lines to be non-segmented A forms a segment bunch (segs: 1->n), from an interval j adds/changes line segment number --------------------------------------------------------------------------- MAIN SCREEN INFORMATION BAR ------------------------------ Left to right, field contents: File name File size First line nmbr in file --> Last line nmbr in file [ max nmbr of lines X max nmbr of chars/line ] Program name Round off factor -- digits to right of decimal point Comma on/off indicator: 0 off, 1 on Line number of top line on present screen Total number of lines on the screen page ---------------------------------------------------- The File Input Routine ------------------------ M03 can function as a text editor program. It can process up to 2001 file records. The program stores the records, for processing, in strings that have a maximum length of 159 characters. If the records are longer than 159 characters, m03 chops them up into segments. These are numbered, are flagged in the edit mode. When the file is output, the segments are put together and the bunches of segments are written as individual records. This chop and glue technology may sound strange, but really does work. On file input, several things happen. First, a number of file lines, to be chopped off the front of the file, is requested. The program will skip these many file lines of the input file, where a file line is up to 159 characters of a file record, but is often simply a file record. Then the file is checked for having binary characters; if so, it is flagged as being a binary file. Always, text formated input is treated as text data & text records. Finally, the file is checked to have been all read in. If not, including any data skipped by request, a lost data report box appears on the main screen. A binary file warning box can also appear on the screen. For binary input, some special characters are converted to blanks; these are the char(7), char(8), char(10), char(13); binary zero's are converted to char(249)'s, the '�'s. This mangles the binary file, but makes the screen print neater. ---------------------------------------------------------------- KEY MEMORY ----------- Several of the keyboard input functions use a memory of previously keyed in strings. The memory uses the regular cursor movement keys: Left, Right, Home, End, Backspace. It uses other keys, as well: Key Function ------- ----------------------------------------- Up scrolls backward thru key memory Down scrolls forward thru key memory F5 deletes memory entry & scrolls backward Enter enters the key input entry F4 moves scroll to the blank entry Tab same as Down key Esc same as Up key F1 same as Enter key F2 same as Left key F3 same as Right key ---------------------------------------------------------------- Key Memory is not hooked up for key input of line numbers; holds around 30 entries; adds no more when full. Other Notes ------------- * An odd message occurs during an i/o use, when the first record of the file is not 1. This is to lessen operator error. * Use lower case for disk letters in changing current directory. * You can use the full path name for the file name to over-ride the current directory. * The program is for all files - but m03 should not be used to update binary files, as some binary data is altered on input. * The len parm of the delete option is for where to chop off the lines. * The comma option will put commas in answers to the arith functions. * Sending a large number digits for division or multiplication is okay - the program will adjust the answer down. * Be carefull with move, it is a tricky function. * Be careful on file output; the 1st and last record figures need to be set for the file in the file area. * The edit wrap around may take some getting use to. It is there so the whole line can be seen on one screen. * The lines per screen may change - the program does this when calculating the optimal number. * The line segments, if any, are re-numbered automatically, starting at one for the first segment. * You can bring in info from the Windows clipboard by using the clipboard portal; then use the Windows DOS screen toolbar for pasting. You can also copy from the DOS screen. see info in Windows Help, under DOS. * Generally, to get out of a function, press the enter key. * m03.exe accepts a file name as an input parameter - it will attempt to open and read in the file, when executed. ----------------------------------------------------------------------
