The LazyBoy library makes it very easy to create extremely complex programs for DOS in assembly language with very little effort. The library will automatically include the various code that is required to support your program and leave out things you do not need or use. There are no massive blobs of unused library code that get linked into your program. Everything gets generated at compile time leaving out the unused code. To be off and creating programs with vesa text mode support with mouse support and much much more, all you need is four lines of code.

Really, that is it. No other includes. No lists of subsystems to initialize. Everything the library provides is now available to your program. The display driver has been initialized. The DOS version has been verified as 5.00 or better. The Stack is prepared. And so, on and on.

Now all that initialization stuff does generate some code. If you do not care about things like windows, mouse, etc., check out the Conditional defines page to see how to disable those.

For those who are nostalgic and want a good old Hello, World! program, here ya go...

However, such a simple program seems bloated with all the overhead for things like Mouse support and the rest. You probably want to trim it down some. So, here is a mimimalist version using some compiler directives.
