By Bob Huelsdonk Only line 30001 is required for less than 32K of Memory. The first GOTO 30000 shows result with greater than 32K of Memory. The second GOTO 30000 shows the result with less than 32K of memory. 30000 IF PEEK (203)>128 THEN 30002 30001 PRINT PEEK (202)+ PEEK (203)*256- PEEK (204)- PEEK (205 […]
This handy little subroutine can be used in two manners; to fill a screen page with repetitive material or to determine the length of a screen page of print statements. Assume line 100 is a print statement with which you wish to fill the page. 100 PRINT” “:GOSUB 400 400 IF PEEK(37) < 18 THEN […]
Don Williams will be our instructor again for two levels of Integer Basic Programming classes available to our members. Beginning and Intermediate classes will be available, with the beginning class starting sometime in August. Details will be available in the next issue of Call-A.P.P.L.E.
As usual, we are down to the wire again as it comes time to write this column. We are still receiving applications from all over the country as we pass the 110 mark in membership, and we would also at this time like to extend a special welcome to our first overseas member, Paul Moortgat […]
A complete program listing is given below to convert a program written in Applesoft I so it will load in Applesoft II. This program is available from the club library, as is a version of Applesoft I with corrections made. Load the converter program in Integer BASIC and RUN. The program will instruct you when […]
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 […]
