The Aldrich brothers strike again. Remember, folks, you read it first in Call-A.P.P.L.E.. “Convert”, by Ron Aldrich using the disk, will create a text file from an Integer BASIC program listing, call Applesoft, and presto, your program has been converted. After Conversion, list it out and note all the lines that need to be changed […]

Here is a quickie about setting up the APPLESOFT ROM card. First, as the instructions indicated, this card will function only in Slot #0 of your Apple ][. This card allows you to make a choice of whether you want Integer BASIC or APPLESOFT to be called with Control-B after you power up. If the […]
Dear Call-A.P.P.L.E. I am writing to say I am very impressed with the Call-A.P.P.L.E. newsletter. It is not only informative, it is also very useful, particularly the section dealing with the System Monitor and Mini-Assembler, since I am especially Interested in Assembly Language. How about making an Assembly Language Tutorial tape. Also, how would I […]
Dear Mr. Golding I recieved my July issue of Call-A.P.P.L.E. after joining the group. I think you are doing a great job on Call-A.P.P.L.E.! In Stopwatch (Library Pak 1A), the display flickers, this can be fixed by changing line 190: Change POKE 34,22 to POKE 34,24. I also have a question that others might be […]
By Bob Huelsdonk When inputting to a double loop by row, then jumping out to a double loop to total by column, it is necessary to revers the subscript order. This will not work in Applesoft BASIC because the right counters do not reset. The following simple example will demonstrate: 80 PRINT “INPUT ‘-1’ TO […]
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 […]
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. Please follow and like us:
By Bob Huelsdonk Some protocol is a must if you use a printer with greater than 40 columns with your Apple. This comes about because it tries to write beyond the screen area and into the variables area in Integer BASIC or into the operating system in Applesoft. The following fix will help prevent this […]
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 […]
