- DFEDIT Version 2.1 Changes
-
-
- This document describes the changes to the DFEDIT version 2.1 tools.
-
-
- General _______
-
- 1. The tools no longer require the support files (*.DAT & *.HLP) to be
- in the directory '\DFEDIT' on the default drive. MS-DOS 2.1 supports a
- 'SET' command which assigns a value to a parameter. The DFEDIT tools
- look for a parameter named 'DFEDIT' whose value should be the pathname
- of the directory where the support files should be found. An example
- set command is given below and indicates the default if none is
- specified.
-
- SET DFEDIT=\DFEDIT
-
-
- Colors ______
-
- 1. Two new colors types have been added to the colors list, 'Border
- lines' and 'Information lines'. Currently the 'Border lines' parameter
- is not used by any tool but the 'Information lines' parameter is used
- by the SHOW utility to display the information between the command line
- and the directory display.
-
- 2. On the TI Professional Computer each color parameter can now be
- displayed in 'Normal' text, 'Reverse' text, or 'Underline' text.
-
-
- Editor ______
-
- 1. The most significant change to the editor was an internal
- implementation change in the way that the file is stored in memory. As
- a result of this change, file loads and saves are much faster. The
- file being edited can also be much larger, limited only by the amount
- of memory available on your machine. Some commands such as Find,
- Replace, and the large Block operations on the other hand are somewhat
- slower.
-
- 2. The Block commands have been enhanced to support Line operations as
- well as Box operations. The Line operations are the same as those
- provided in earlier version of DFEDIT. The Box operations allow a box
- of text to be Copied, Deleted, or Moved. The Box is selected with the
- 'Block' function by marking the upper/left and lower/right corners of
- the box or the upper/right and lower/left corners of the box. The mode
- of the 'Block' command is selected by the 'Box mode' or 'Line mode'
- commands.
-
- 3. A Center Line 'CenLn' function has been added which centers the
- text on a line between the left and right margins. This function is
- assigned by default to the 'alt-C' key.
-
- 4. A Fill Paragraph 'Fill' function has been added which fills the
- text in a paragraph to the right margin. The end of the paragraph is
-

-
-
- indicated by a blank line or end-of-file. This function is assigned by
- default to the 'alt-F' key.
-
- 5. A Set/Reset Tab 'SetTb' function has been added which sets a tab or
- clears a tab at the current cursor column position. This function is
- assigned by default to the 'alt-T' key.
-
- 6. Since several key functions have been added, the DFEDIT 2.0
- 'EDITKEYS.DAT' will work with the new version but the new functions
- will not be assigned.
-
- 7. A new 'Modify' command has been added which allows the 'Colors',
- 'Keys', 'Options', and 'Tabs' to be changed. This command replaces the
- old 'Keys' and 'Tabs' commands.
-
- 8. A new set of editor 'Options' have been added which are saved in
- the file named 'EDITOPTS.DAT'. The options can be modified by moving
- to the desired option and selecting the 'Modify' command. These
- options are listed below:
-
- a. Backup file as '<name>.bak' - Each time a file is replaced, the
- old version of the file is saved with an extension of 'bak'. This
- option can be selected by specifing 'Yes' or not selected by
- specifing 'No'.
-
- b. Floating 'Return' key - Each time the 'Retrn' function is used,
- the cursor normally moves to the first character on the next line.
- This option will allow the cursor to always move to the left margin
- rather than the first character. The normal floating return can be
- selected by specifing 'Yes' or the fixed return can be selected by
- specifing 'No'.
-
- c. Horizontal scroll size - The amount by which a wide file moves
- left and right within the display window is controlled by this
- parameter. The number of columns by which the file should be
- scrolled must be specified.
-
- d. Left margin - The value of the left margin must be specified.
-
- e. Right margin - The value of the right margin must be specified.
- It cannot be greater than 256.
-
- f. Use tabs to pack line - Whenever a new line is added to a file
- or modified it can be packed using tab characters. Line packing
- using tab characters is selected by specifing 'Yes'. Blank
- character packing is selected by specifing 'No'.
-
- g. Vertical scroll size - The number of lines by which the Page Up
- 'PgUp' and Page Down 'PgDwn' functions scroll the file in the
- display window is controlled by this parameter. The number of
- lines by which the file should be scrolled must be specified.
-
- 9. All prompts in the 'Edit' or 'Show' utility now use the Editor key
- mappings. Therefore you can now insert special characters into prompts
- if you need to find a form feed character for instance.
