Looks like every bit in the file is used ;-) History ------- BDCK 1.0 -------- by Andreas Rost, Happy Computer 6/1988 (German version w/o online help, not self-explaining: you have to read the whole article) typed in by Peter Meier with little help from FineReader Fixed typos / annoyances ************************ No blank after DATA (bdck1.bas:350-370, bdck4.bas:125) No blank after DEFINT (bdck3.bas:30) Wrong filename (bdck2.bas:30,305,400) Dead code after RETURN/END (bdck1.bas:530, bdck2.bas:400, bdck3.bas:3410) Undocumented feature: Save custom runnable game file (bdck2.bas:305) The listings bdck5.bas and bdck6.bas were mixed!!! (beginning at line 680) You have to save your level to disk and then load it again to play it, although it is still in memory. Possibly unreachable code (bdck2.bas:400) Joystick supported to move cursor, but not to change line length with SHIFT (fixed in 1.1) <TAB> key in editor does nothing (unfixed even in 1.1) Discussible features ******************** RAM disk support Full support for Vortex RAM Disk: ùM, ùMD, ùDLOGIN Partial support for Drive C RAM disk (Happy Computer 10/1987): ùC (not all files converted, will not work without further adaptations, see magazine article) Load/save levels from/to memory No, this is not the same as a RAM disk... (A RAM disk behaves like a drive) NOTE: I left both features untouched. Even in version 1.1. Although I always have to confirm "I want to load from disk, not from memory!!!" BDCK 1.1 -------- by Peter Meier 2/2013 (English version with online help, self explaining) Fixes / improvements ******************** Translated all texts into English (the key codes remain the same) Support joystick to change line length with SHIFT (bdck1.bas:420) Added additional help texts Added note about level names (bdck3.bas:121) Added key 'p' for online helP (bdck3.bas:1070,1235) Added two pages online help text (help.bas) Added note about filename prefix PICT (bdck3.bas:2720) Show "progress bar" while initializing levels (bdck1.bas:211) Reduced interactions: Don't ask for a filename before the editor is started: bdck11.bas) Don't ask for a filename before the game is started: bdck21.bas) Don't ask for infinite lives before the game is started: bdck21.bas) Don't ask to save a custom game before the game is started: bdck21.bas) Always use color screen (bdck3.bas:3240) Removed dead code after RETURN/END Disabled <DEL> key (bdck3.bas:1250) Support lowercase key 'q' (bdck3.bas:1230) Catch file not found error (bdck3.bas:2720) Catch disk missing error (bdck3.bas:360) Use ùdir instead of cat, otherwise the selected drive is ignored (bdck3.bas:360) TO WHOM IT MAY CONCERN: My intention was to keep 1.0 and 1.1 diff'able.
