By Val J. Golding Applesoft & Applesoft II store in memory from the bottom up, unlike Integer BASIC, which is just the opposite, storing from the top down. Although pointers and characteristics of Applesoft I and II are similar, they are different. Therefore we will limit ourselves to APII in this discussion. Programs store startirlg […]

By Darrell Aldrich While written for Applesoft II, this article is also applicable to Integer Basic HIRES graphics mode. The High Resolution Graphics screen is composed of 280 vertical bars (X coordinates), by 160 units high (Y coordinates). The even-numbered bars are violet in color, while the odd-numbered bars are green. The color white is […]
We will have available sometime within the next month the Applesoft II version of Programmers Workshop, with most of the same routines, Append, Renumber, Examine Basic, Pick a Base, Poke writer. Pricing has yet to be determined.
By Val J. Golding Here are simple routines that will allow you to append programs in both version of Applesoft. While appending can be done under program control in App. II, it is really simpler to do it without. The routines are the same in both versions; only the pointers have been changed (to protect […]
By Don Williams One of the minor deficiencies in Apple Integer BASIC is the omission of the Data statement. In search of a remedy for this, I wrote a program to save memory in a BASIC string assignment. This is listed as program lines 1020 through 1190. Upon embarking on the first routine, I quickly […]
by Dana Redington = Apple Computer, Inc. More word on the utility Rom. In addition to the routines previously mentioned, this Rom will have new high-res operating routines, including a SHAPGEN command that will eliminate the need to manually write HIRES vectors. You will be able to directly address a d0t matrix, and there will […]
