PRODUCT : TURBO BASIC NUMBER : 361
VERSION : 1.0
OS : PC-DOS
DATE : July 22, 1987 PAGE : 1/2
TITLE : PATCH FOR INPUTTING EXTENDED ASCII CHARACTERS
Alt-Char patch to TURBO BASIC 1.0
Turbo Basic currently ignores non-standard characters (outside
the range of 20h - 7Eh) ) entered via an INPUT statement. This
patch corrects the problem, allowing those characters to be
entered properly.
How to install the patch:
1. Rename the compiler file (TB.EXE) to TB.ABC using the DOS
'ren' command:
ren TB.EXE TB.ABC
2. Start up DEBUG by typing DEBUG TB.ABC at the DOS prompt
(>).
3. Display the contents of the CS register by typing the R
command at the DEBUG prompt (-):
R CS
4. Use the Hexarithmetic command to add 1000 (hex) to this
value. For example:
-R CS
CS 34F7
: <--- you press RETURN here
-H 34F7 1000
44F7 24F7
^---- 44F7 is the sum of CS (34F7) and 1000 (hex)
5. Next, use the sum above as the segment for the following
Enter command:
e xxxx:4e34 d8
^---- where this is the sum from above (44F7 in example)
6. Now save the file using the 'w' command (at the DEBUG
prompt, enter:
PRODUCT : TURBO BASIC NUMBER : 361

OS : PC-DOS

w
7. Quit the debugger by entering the 'q' command at the
DEBUG prompt:
q
8. Finally, rename TB.ABC back to TB.EXE:
ren TB.ABC TB.EXE
