. EDA - INTRODUCTION . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ EDA is a text editor intended for large ASCII files. It has special functi- ║ ║ ons, which enable to perform calculations, sorting, block-based editing etc. ║ ║ EDA uses all free memory RAM to create large page. Width of this page ║ ║ (maximal number of characters per line) is defined by user at DOS prompt as ║ ║ a parameter. Length of page (maximal number of rows), which EDA can handle, ║ ║ depends on the page width according to the following rule: ║ ║ ║ ║ (width of page + 2) x (length of page) = size of free memory RAM. ║ ║ ║ ║ In spite of this rule, length of text page cannot exceed 24000 rows (32000 ║ ║ rows in protected mode version) and text page width cannot exceed 24000 ║ ║ characters. ║ ║ ║ ║ EDA is written in Borland's Turbo Pascal and there are two versions. First ║ ║ is compiled for DOS real mode and can handle files up to 500KB. Second ver- ║ ║ sion is compiled for DOS protected mode and size of file depends on extended ║ ║ memory size. For example, if your computer has 8MB RAM, you can handle files ║ ║ up to 7MB. Most of the special functions are based on the block definition, ║ ║ that is rectangular area defined by upper left corner (start of the block) ║ ║ and lower right corner (end of the block). If the block is correctly defi- ║ ║ ned, it is marked by inverse display (black text on white background). ║ ╚══════════════════════════════════════════════════════════════════════════════╝ . EDA - HOW TO RUN PROGRAM . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ EDA can be run at DOS prompt using command: ║ ║ ┌────────────────────────────║ ║ EDA [param1]/[*] [param2] │ To find the longest row in ║ ║ │ unknown text file, type: ║ ║ param1 = name of input file │ ║ ║ param2 = page width (default 254 characters) │ FI file_name ║ ║ │ ║ ║ │ at DOS prompt ║ ║ Examples: └────────────────────────────║ ║ ║ ║ C:\>EDA * 120 - new text with page width 120 characters will be edited ║ ║ C:\>EDA MER.1 - file MER.1 will be edited with page width 254 characters ║ ║ C:\>EDA MER 3000 - file MER will be edited with page width 3000 characters ║ ║ ║ ║ When exiting EDA (Esc key), the following question appears: ║ ║ "save ? (y/n/file name)" ║ ║ or, if new text was edited: ║ ║ "save ? (n/file name)" ║ ║ If the answer is y (yes), the input file will be replaced by contents of the ║ ║ text page. If n (no) is entered, EDA will exit without saving the text. ║ ║ If new file name is entered, EDA will save text into file with this name. ║ ╚══════════════════════════════════════════════════════════════════════════════╝ . EDA - SCREEN DESCRIPTION . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ As soon as EDA is started from DOS prompt, first twenty four rows of input ║ ║ file appears on the screen.

EDA - BLOCKS . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ Block is defined using keys F7 (start of the block - upper left corner) and ║ ║ F8 (end of the block - lower right corner). Let c1 and r1 designates column ║ ║ and row of the block start, and c2 and r2 designates column and row of the ║ ║ block end. Block is correctly defined, if and only if s1<s2 and r1<=r2. ║ ║ ║ ║ Correctly defined block is marked by inverse display (black text on white ║ ║ background). If Ctrl+U is pressed, block is not visible by inverse display, ║ ║ but it remains defined - inverse display is restored using Ctrl+D. For easy ║ ║ change of long blocks there are keys Ctrl+F7 and Ctrl+F8, which are intended ║ ║ for initial and terminal column change (row range of the block is not chan- ║ ║ ged). ║ ║ It is possible to copy (move) block into another place using key F9 (F10). ║ ║ Block is copied (moved) so, that upper left corner of the copied area is ║ ║ identical with cursor position. This function is realized only in replace ║ ║ mode - that means, if there is any text in destination area, it will be re- ║ ║ placed. In cases, when text has not to be replaced, it is necessary to ║ ║ create free space using keys Enter or Ctrl+Enter. ║ ║ There is possibility to copy (move) block in horizontal direction using key ║ ║ Ctrl+F9 (Ctrl+F10). ║ ║ For reading and writing block contents from/to disk are intended keys ║ ║ Ctrl+R and Ctrl+W.

EDA - MATRIX MODIFICATIONS . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ Key Ctrl+X enables to perform operation with all elements of the matrix: ║ ║ multiplication by constant, constant addition and absolute value. Key Ctrl+T ║ ║ enables matrix transposition (exchange rows and columns).

Reading ║ ║ from disk must not be always complete (in this case adequate warning is ║ ║ displayed), especially if long rows or long columns are transposed. In any ║ ║ case, user has available files MUL.MAT and TRA.MAT.

EDA - CACHE FOR FREQUENTLY USED WORDS . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ Frequently used words can be recorded into special file named CACHE.EDA in ║ ║ actual directory. If key F4 is pressed, word at cursor position is recorded ║ ║ into file CACHE.EDA and from this moment it is available for quick transfer ║ ║ into written text. After EDA is started, cache buffer with frequently used ║ ║ words is not visible. If key F3 is pressed, EDA starts to check each written ║ ║ word. When first letters of the word are typed, EDA looks up words beginning ║ ║ with these letters in the cache buffer. If there are such words, they are ║ ║ displayed in opened upper window and marked by yellow letters on green back- ║ ║ ground. User can press key Tab, select (using keys ¬, ½, º, ô) desirable ║ ║ word, and by pressing Enter can transfer word into text. Word can be also ║ ║ transferred with key corresponding to yellow mark (keys a,...,h). If there ║ ║ is only one word in cache buffer (beginning with typed first letters of the ║ ║ word), EDA peeps and calls attention to opportunity for transferring of the ║ ║ word. ║ ║ ║ ║ If this EDA's feature is intensively used, it is reasonable to create ║ ║ several files with frequently used words concerning with certain topics. ║ ║ These files can be named according to user convenience and before using EDA, ║ ║ desirable file can be renamed to CACHE.EDA. File CACHE.EDA is ordinary ASCII ║ ║ file and can be created by any ASCII editor. If there is too many words in ║ ║ CACHE.EDA, looking up words may unacceptably slow down. ║ ╚══════════════════════════════════════════════════════════════════════════════╝ . EDA - NON-STANDARD CHARACTERS . ╔══════════════════════════════════════════════════════════════════════════════╗ ║ Key Ctrl+Q is intended for input of any ASCII character.

Such file can then be used as an input file for ║ ║ database programs (dBASE, FOXPRO,...) or for spreadsheets (QPRO, LOTUS,...). ║ ║ EDA determines width and number of the decimal places in number-columns. ║ ║ Also determines the date in the format DD.MM.YY - day, month and year (as ║ ║ a delimiter, character ".", "/" or "-" can be used). Columns containing only ║ ║ numbers will be transformed as a numerical items, columns containing only ║ ║ date will be transformed as a date items and in the other cases, columns ║ ║ will be transformed as a character items. Names of the items can be listed ║ ║ in the separate file file_name.HDF (file_name is the name of edited file ║ ║ without extension) in actual directory (each name of item must be on the ║ ║ extra row - do not forget to satisfy conventions for names of DBF items!). ║ ║ It the file lile_name.HDF does not exist, EDA will create it's own names. ║ ║ ║ ║ Program AFV can be used as a ASCII file viewer.
