System anomal behavior or what to expect and what no:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 1. SetKey(...)    --> doesn't work for ALT-D

 2. ALT-C          --> immediate abort of program and return to DOS

 3. StuffKey(nKey) --> the queue is not erased and can be modified wrong
                       when containing InKey codes out of (0..255)

 4. CLASS... and  METHOD...  definitions of the same class should be in one
    separate file.
    The reason: identifier names colision (only for Class(y), o:Clip has'nt
    this problem but it is recomended to follow this rule.

 5. Error with text (DOS Error 4) is caused by low number of FILES in
    config.sys or low number opened files in SET CLIPPER=... in
    autoexec.bat
