I realize that not all the TP people have yet gotten 6.0, but I have a Turbovision question. They supply an editor object (demonstrated in TVEDIT.PAS in the TVDEMOS directory) which won't allow me to type using the keys 3 4 5 6 or the shifts of those keys # $ % ^. Their demo has the same problem as my program. The Turbo Editor in the IDE has no problem with those keys. Any ideas as to what's going on. Can someone else confirm this problem? (It occurred for me on 2 different PC's with different keyboards.) David Rind rind@popvax.harvard.edu

(It occurred for me on 2 different PC's with >different keyboards.) Yes, it happens on my machine as well. I traced down the bug to the procedure ScanKeyMap. The problem was the scan code for a 3 is $0433 but was getting set to a Ctrl-Ins (kbCtrlIns = $0400). The code was checking only the high byte of the scan code. The fix is one line in the Editors.Pas source code (see below) ------------------ Fix to ScanKeyMap -------------------------------------- function ScanKeyMap(KeyMap: Pointer; KeyCode: Word): Word; assembler; asm PUSH DS LDS SI,KeyMap MOV DX,KeyCode CLD LODSW MOV CX,AX @@1: LODSW MOV BX,AX LODSW OR BL,BL JE @@2 CMP BL,DL JNE @@3 OR BH,BH JE @@4 @@2: CMP BX,DX { this is the line, had been: cmp bh,dh } JE @@4 @@3: LOOP @@1 XOR AX,AX @@4: POP DS end; ----------------------- End of Code ---------------------------------------- This fixed the problem for me. Note: I'm not positive if the pascal style comments work with the inline assembler or whether you need TASM style comments.

Off hand, don't they give you the source for TVEDIT? If they do, you might be able to fix it on your own. This is a very obvious bug. It does look like some of the final QC was rushed. bruce -- | Bruce O'Neel | internet : oneel@heasfs.gsfc.nasa.gov| | Code 664/ST | span : lheavx::oneel | | NASA/GSFC |compuserve: 72737,1315 | | Greenbelt MD 20771 | AT&Tnet : (301)-286-1119 |

Sorry to follow up my own article, but I got in touch with Borland via Compuserve, and this is a known bug and they have a patch available. David Rind rind@popvax.harvard.edu
