Q31072: FUNCTION+NUM LOCK Toggle Remaps Cursor Keys on Toshiba T1200
Article: Q31072 Product(s): See article Version(s): 4.00 4.00b 4.50 Operating System(s): MS-DOS Keyword(s): ENDUSER | B_BasicCom | mspl13_basic Last Modified: 28-DEC-1989 The Toshiba T1200 computer is not officially supported by QuickBASIC. The dedicated cursor keys on the Toshiba T1200 may not work correctly with the QB.EXE Versions 4.00, 4.00b, and 4.50 editors, except as explained in a separate article in this database. For more information, query on the following words: Toshiba and dedicated You can obtain an alternative set of working cursor keys on the Toshiba T1200 by using FUNCTION+NUM LOCK as a toggle to activate a 10-key keypad in the middle of the regular keyboard, as shown below. Also, according to Toshiba Product Support, the Toshiba T1200 comes with a program called SETUP1.EXE or SETUP12.EXE that has a 101-key installation option that makes the cursor keys behave normally (even though the Toshiba only has 84 keys). The Toshiba T5100 and Toshiba T3100 come with the program TEST3.EXE, which serves the same purpose. This information applies to QuickBASIC Versions 4.00, 4.00b, and 4.50, to the QuickBASIC editor that comes with Microsoft BASIC Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2, and to the QBX.EXE editor that comes with Microsoft BASIC PDS Version 7.0 for MS-DOS and MS OS/2. When running QB.EXE (or QBX.EXE from BASIC PDS Version 7.00) on the Toshiba T1200, you can activate a 10-key keypad in the middle of the typewriter keyboard by holding down the FUNCTION key and pressing NUM LOCK. Subsequently pressing NUM LOCK alone switches between numbers and cursor functions. To return to typewriter mode, press FUNCTION+NUM LOCK again. The numeric keypad is mapped as follows: Typewriter Keys Numeric Cursor --------------- ------- ------ 7 8 9 7 8 9 HOME UP PGUP U I O 4 5 6 LEFT ---- RIGHT J K L 1 2 3 END DOWN PGDN M , 0 . INS DEL ---- Selecting text and performing other cursor-oriented features of QuickBASIC Version 4.00 works correctly using the above regular keyboard keys as your keypad, instead of using the dedicated cursor keys.
