- In general, I am not inclined to jump ahead to later material in the
- book that I am writing. But, since I do support the concept of encourage-
- ment to the extent that it might alleviate the task of learning assembly
- language; and, since I promised R. Gillies that I would upload a desk
- accessory example, I am yielding this program as an example of the type of
- material that will presented in later chapters of "Atari ST Machine Specific
- Programming In Assembly".
-
- This desk accessory installs a print buffer and interrupt handler that
- are designed to get one out of the application FAST. The usual circular
- print buffers are too slow. After all, the reason one should be using a
- print buffer, in the first place, is that one is envolved in some work that
- demands a quick return to what is being done; yet a hard copy of something
- is desired.
-
- This buffer handles one file at a time. Many enhancements could be
- added; for example, a file queue to support the sequential printing of
- multiple files. But that is not the purpose of this example. It has been
- designed to serve as an uncluttered example of a practical desk accessory.
-
- The documentation within the source file should be sufficient for those
- who are not content to wait until I get to the material in the book. If not,
- you are on your own. But there is a lot of other material around. Look in
- magazine articles and gem books.
-
- To use the accessory, just copy PRTASCII.ACC to the root directory of
- your boot disk, or call it up from within MultiDesk. Have your printer on,
- your computer packed in dry ice and a fire extinguisher standing by--cause
- this sucker moves.
