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 Val J. Golding This routine will allow you to format Applesoft REM and PRINT statements on screen without having to worry about the lines being different. One item to take note of: This program only works in 40 column mode in this format: 10 REM ROUTINE TO FORMAT REMARKS LINES AND PRINT STATEMENTS IN […]
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 […]

NOTE:Values 00 to 7F (0 to 127 decimal) are used by the standard Ascii character set. As in Integer BASIC, Apple II outputs last two rows (60-7F) as uppercase. This table is a complement to “Applesoft II Pointers and Tokens on Pages 6 & 7, and should be saved as a permanent reference chart.
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 […]
