         for the creation and maintainance of this CodeFAQ
      Suggestions, questions, and answers from everyone in
                   QUIK_BAS, too many to list.
  If you use code or ideas from here, make sure you give credit
                      where credit is due.
 New in this FAQ:
   No new topics this time.  Sorry, it's early this time around.
   Will post on the 15th next month, as expected. Computer problems!!
 Topics covered in the Code FAQ:
   0) Introduction
   1) What are TYPEs, and how do I use them?
   2) What are SUBs and FUNCTIONs, and how do I use them?
   3) How can I produce a delay in my program independent of the
      CPU speed?
   4) What are INTERRUPTs, and how do I use them?
   5) Can I use INTERRUPTs with QBasic?
   6) How do I use the mouse in QB?
   7) How can I check for the existance of a certain file?
   8) How do I perform a cold/warm boot through QB?
   9) How can I print text in a graphics mode without destroying
      the background?
  10) How can I animate sprites in QB?
  11) Can I use VESA screen modes in QB?
  12) Can I create a TSR in QB?
  13) How can I make QB exit with an error level?
0) Introduction
   This is the Code FAQ!  Hopefully your most common questions will
   be answered by this document.  If not, go ahead and ask us at
   the FidoNet QUIK_BAS echo, or e-mail me (Robert Kohl) and
   I'll get an answer from them (or, less occasionally, from
   myself).
   All full program pieces of code in this FAQ are designated by
   the [begin] and [end] markers.  Just copy the code in between
   these two lines into your QB program, and it's ready to go!
   Note:  Any time you see code with an underscore ("_") at the end
   of a line of code, you may need to connect the two lines
   surrounding it if QB doesn't do it for you automatically.  For
   instance:
   PRINT "hello wo_
   rld!"
   Should be:
   PRINT "hello world!"
   One more thing:  any time you see the use of INTERRUPTs in a
   piece of code, be sure to load QB with the /L switch.
   Example:  qb newcode.bas /L qb.qlb
   ...Enjoy!
1) WHAT ARE TYPES, AND HOW DO I USE THEM?
   The TYPE statement lets you create your own data type, in
   addition to QB's integer, double precision, and string types,
   to name a few.  You create a name for this new data type,
   and you can then make a list of normal variables that will
   become sub-variables in your TYPE.  Think of a TYPE as a
   variable itself, and then the sub-variables as answering the
   question, "which part of that TYPE?"  TYPEs are very good
   at organizing many different variables into one recognizable
   area.  Here's an example of a TYPE:
   TYPE ScreenType
      X AS INTEGER
      Y AS INTEGER
      Color AS INTEGER
      Text AS STRING * 20
   END TYPE
