- NPAD (Notepad) Steven Holzner
- Command PC Magazine Vol 3, No 25
- Copyright 1984 Ziff-Davis Publishing Company
- ______________________________________________________
-
- Purpose: Creates an on-screen window in which to keep
- notes while working in other programs.
-
- Format: NPAD (loads memory-resident program)
- <Ctrl-N> (toggles notepad on/off)
-
- Remarks: The NPAD notepad holds 10 lines of 25
- characters each. The window is toggled on
- and off in the upper right corner of the
- screen. Toggling the window off does not
- eliminate its contents, but pressing the
- Delete key while the window is on-screen
- does. Single characters may be deleted with
- the backspace, and the carriage return is
- also recognized. No provision for storing
- the contents of the notepad as a file are
- available, however.
-
- Option 1: NPAD.COM can be modified by using
- DEBUG. The ASCII and scan codes for the
- default trigger key (Ctrl-N) are 0Eh and 31h,
- respectively, and are located at the offset
- addresses xxxx:0336 and xxxx:0337. To change
- these to use the reverse apostrophe (grave
- accent), you would enter
-
- DEBUG NPAD.COM
-
- and
-
- -E 336
-
- DEBUG will respond with
-
- xxxx:0336 0E.
-
- and you simply type in the new ASCII code, in
- this case, 60 (the hex value of decimal 96).
-
- After entering E 337 and getting the response
-
- xxxx:0337 31.
-
- you type in the new scan code 29 (41 decimal)
- for the grave accent. Other ASCII and scan
- codes are given in the BASIC and in the DOS
- Technical Reference manuals.
-
- The two locations to examine and change for
- the NPAD colors are 02FF and 0413, which have
- a default value of 70h (112 decimal). On a
- color monitor this produces a white (7)
- background with black (0) characters. For
- red letters on white you would change the 70h
- to 74h (116 decimal) at these two locations.
-
- The colors to which NPAD resets its portion
- of the screen on exit are set by the value at
- xxxx:0350h. The default value is 07 (white
- characters on a black background). For white
- letters on a dark blue background, change the
- 07 to 17h (23 decimal); for dark blue letters
- on white, use 71h (113 decimal) at this location.
-
- When you have made the changes you want, at
- the DEBUG hyphen prompt enter W and then Q.
-
- Notes:
-
- 1. NPAD is a memory-resident program that
- must scan the keyboard interrupts. It
- will conflict with applications programs
- (e.g., XyWrite) that themselves
- commandeer the keyboard interrupts.
