CODE CLINIC #1:    UP THE HILL...


 

-------------------------------------------------------INTRODUCTION




       
        It seems like only yesterday, I was slaving away at C64  Basic
 (1983) and knew that someday I would learn to write killer code; Then I
 bought an A500 (1989) and began rewriting my 64Basic to AmigaBasic, again
 I knew that someday I would write killer code. 
 
        I now own an A1200 and SAS/C 6.0 (waiting for my upgrade to 6.5). 
 I own several books with titles such as C by example and Teach yourself 
 C, and while these books are very helpful in learning the C language, you 
 will not be writing killer code by the end of the exercises. 

        In this column I will try to guide you "up the hill" to writing
 killer C code.  This column is not for beginners, it's assumed you have 
 an understanding of ANSI/C coding.  If you don't, any bookstore will have 
 books such as the ones I listed above. I myself will be learning new 
 skills as we go "up the hill."  Oh yeah, our goal is to reach the top.



 -------------------------------------------------------------PREP



     #include <stdio.h> 
        main() 
        { 
                printf("HelloWorld\n"); 
        }
        

     This is the first code every C programmer will learn. In this first 
 column we will `Amigatize' this code.  Basically, when I say `amigatize' I
 mean use Intuition.  Intuition is defined in the ROM Kernel Manual-
 Libraries as: the collective name for the function libraries, data 
 structures and other elements needed to create a graphical interface for 
 Amiga applications, AMIGATIZE!!!



        How would you `amigatize' this simple program? 



        Here is a list of things we will do to make this an Amiga program.

        o OPEN A WINDOW IN WORKBENCH WITH A           
          CLOSEGADGET TO END THE PROGRAM.
 -----------------------------------------------------------LETS GO-

        This article is intended for NEW Amiga C language coders.
        Those of you who have genius IQ's, forgive us mere mortals.

        OK, with all that out of the way lets' dive into some code!
