以前的帖子上曾经发过一个表：
quick basic 的键盘控制很简单
下面我给你一个列表：
      Key       Code      Key         Code        Key         Code
      Esc        1         A           30          F1          59
      ! or 1     2         S           31          F2          60
      @ or 2     3         D           32          F3          61
      # or 3     4         F           33          F4          62
      $ or 4     5         G           34          F5          63
      % or 5     6         H           35          F6          64
      ^ or 6     7         J           36          F7          65
      & or 7     8         K           37          F8          66
      * or 8     9         L           38          F9          67
      ( or 9    10         : or ;      39          F10         68
      ) or 0    11         " or '      40          F11        133
      + or =    13         Left Shift  42          NumLock     69
      Bksp      14         | or \      43          Scroll Lock 70
      Tab       15         Z           44          Home or 7   71         (数字指的是小键盘)上数字)
      Q         16         X           45          Up or 8     72
      W         17         C           46          PgUp or 9   73
      E         18         V           47          Gray -      74
      R         19         B           48          Left or 4   75
      T         20         N           49          Center or 5 76
      Y         21         M           50          Right or 6  77
      U         22         < or ,      51          Gray +      78
      I         23         > or .      52          End or 1    79
      O         24         ? or /      53          Down or 2   80
      P         25         Right Shift 54          PgDn or 3   81
      { or [    26         Prt Sc or * 55          Ins or 0    82
      } or ]    27         Alt         56          Del or .    83
      Enter     28         Spacebar    57      
      Ctrl      29         Caps Lock   58      
举个例子：
Ctrl 值是 chr$(0)+chr$(29)  del 值是 chr$(0)+chr$(83)
你在前面加上 Chr$(0) 就可以了


　　                              但是我看到qb45发的一个程序：

cls
locate , ,0
DO
   DO: k$ = INKEY$: LOOP UNTIL k$ <> ""
   LOCATE 10, 1: PRINT SPACE$(80)
   SELECT CASE k$
           CASE CHR$(27)
             LOCATE 10, 1:PRINT "你按了ESC建"  
           CASE CHR$(0) + chr$(75)
             LOCATE 10, 1:PRINT "你按了左建"  
           CASE CHR$(0) + chr$(77)
             LOCATE 10, 1:PRINT "你按了右建"
           CASE CHR$(0) + chr$(72)
             LOCATE 10, 1:PRINT "你按了上建"    
           CASE CHR$(0) + chr$(80)
             LOCATE 10, 1:PRINT "你按了下建"  
           CASE chr$(8)
             LOCATE 10, 1:PRINT "你按了BACK建"  
           CASE CHR$(0) + chr$(83)
             LOCATE 10, 1:PRINT "你按了DEL建"  
        END SELECT
      LOOP



这个程序上的ESC键是怎么搞的？没有用CHR$(0)＋.....　　还有，我发现好像CHR$(0)+CHR$(1--10)都没有作用，怎么回事？请帮我解答一下！
