“Alphabet Soup”

By Dave Kelly

“Alphabet Soup”

Welcome to Basic School! This article is dedicated to those of us that enjoy programming in Basic. Programmers of structured languages have put Basic down for several years because it is not considered a structured programming language and many implementations of Basic lack enhancements which give it power to perform advanced functions. Also it has been said many times that it is much harder to follow the program flow in Basic than in other languages like Pascal. Those who complain about the limitations of Basic are sometimes quite justified in their complaints. After all, basic “BASIC” isn’t very powerful and not very flexible at all. Any enhancement at all is an improvement. This has been the caseup until now. Now, the enhancements that we find in Macintosh Basic are approaching the power of the more acceptable high level languages such as Pascal. Exploring Macintosh Basic computing power is what this column is all about.

In the last few months we have seen the evolution of the programming tools needed to program the Mac on the Mac. In the coming issues, we will explore the enhancements included in the new MacBasic and in Microsoft Basic Version 2.0. At the writing of this article Microsoft tells me that they intend to release Microsoft Basic Version 2.0 by the end of October or sometime in November. I’m told that it includes many enhancements which in my opinion should have been included from the very first introduction of Microsoft Basic to the Macintosh world. These enhancements include programmable windows, menus, scrolling, sound and sound effects, compatability with MacWrite, complete mouse control, editing, debugging, access to most if not all of the Mac internal ROM routines, and elimination of the need for line numbers. This is what I call programming made easy. From what I’ve seen so far, there will be quite a competition between MacBasic and Microsoft Basic 2.0 in the coming months.

The Mac Basic listing shows an example of the ease in documenting a program as it is written. I originally wrote the program in Microsoft Basic version 1.0 as an educational tool for my 2 year old to learn his alphabet. The program prints the alphabet and then prompts the user to find each letter one at a time.Then the user points to the letter with the mouse and presses the mouse button. By using variable names that show what is happening and by the use of line labels the program requires little documentation. When I write programs, I rarely have the time to finish up with documentation especially when my 2 year-old can’t wait to start the game. The use of these labels will be familiar to anyone who has used Basic on the Hewlett Packard 9826-36 series computers. The label name is used in each of the gosub statements in place of the line numbers. This makes the use of line numbers unnecessary. The coresponding label name also appears at the beginning of the subroutine followed by a colon. By indenting the text of the program within each subroutine, it is clear where the subroutine starts and ends and the label gives a clue as to what each subroutine does.

Next month we will explore Basic programming on the Mac in more detail.
