    Technical Notes

    Fast Library For Clipper in older versions was written 100%
 in Clipper code 5.x. Actually a great part of its code is written
 in assembly code, and C, to concrete, referred to the mouse,
 communications, graphics, video, Sound Blaster, timer, cmos and many more.

    The inclusion of non Clipper code it is neccesary because everyone
 knows that Clipper standard libraries do not have functions for using
 interrupts.

    The code of Fast Library For Clipper does not use neither Public
 nor Private variables trying to avoid this way the heap memory overload of
 Clipper.

    The space of the library global overhead has been considerably reduced
 over older versions in a way that the Linker just gives to the executable
 program what it needs.

    We don't use neither macro-replacements nor commands or precedures, all
 we use are functions.

    I have insisted on the use of "codeblock" as a communication way
 between the inside functions of Fast Library because it is a very easy,
 fast and parametrizable method. Anyway due to the easiness of last user
 functions they will not be used as an argument, they will be used as
 numerical, character, logical an array data types.

    About the documetation, I have to say that I have followed a very
 well known and acepted sintax in the computers world, I mean the
 Backus-Naur-Form (BNF). However in this Norton Guide I have used
 the Chomsky-Naur-Form to generate graphics in this device.

    Someday we will have audio-visual documentation and this old forms will
 not have any sense, meanwhile we will continue using everything that
 mathematicians give to us.

    Either the code used in the documentation examples and this guide's
 ones are always in Hungarian form because I think this is the best
 one. It is very easy and legible.
 Let's thank to Microsoft for expreading this form.

    All variable argument names in Fast Library For Clipper are prefaced
 by a lower case letter. This letter denotes the type of variable:

        c  ->  denotes a character string
        n  ->  denotes a numeric value
        l  ->  denotes a logical (.T./.F.) value
        d  ->  denotes a date value
        a  ->  denotes an array value
        o  ->  denotes an object

    Arguments to function which are enclosed in brackets [] are optional to
 the function.
