By Val J. Golding APPLESOFT I I Extended Precision Floating Point Basic. $20 from Apple dealers or direct from Apple Computer, 10260 Bandley Drive, Cuptertino, CA 95014. Supplied free with new 16-48K Apples. A ROM version is expected to be released about July 1st for $99. One’s first impression might be that charging for this updated version of Applesoft is unfair, which was our snap judgement. However, consideration must be given to other facts, the first being that Apple Computer…

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 APPLESOFT II BY VAL GOLDING – 5.20.1978 20 REM APPLE PUGETSOUND PROGRAM LIBRARY EXCHANGE 6708 39TH AVE SW SEATTLE, WA. 98136 90 HOME:VTAB4 100 PRINT…

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 to load your Applesoft I program.  When the conversion is complete and you have re-saved your Applesoft I program, load it into Applesoft II and…

The May 1978 Contact! newsletter from Apple Computer, Inc. contained a number of required patches to repair bugs in Applesoft I. Array Indexing Problem Fix Long line Fix “END” Statement Fix FRE(0) Function Fix

……is the name of a new monthly newsletter published by Apple Computer, Inc.  The first issue (May 1978) was literally packed with good information and programming hints. If you did not get your copy int he mail, be sure to contact your Apple dealer.

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 at decimal location 12289 upwards, at’Id variables are located starting at the high end of program storage. Where there is no program present, theh the…

June 1978 To all A.P.P.L.E. Members: please note that our library now has a LCOS (Limited Cassette Operating System) for all of our cassette based programs.

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.

The Apple ][ is country’s best seller?  This is what Phil Roybal, Apple Computer’s marketing manager expressed to us when we asked him recently.  Apple’s new Shuggart mini-floppy has now been officially announced at an unbelievably low $495.  The Delievery is scheduled to commence in lat June.  This drop of $200 was enough to influence our decision to buy. The Applesoft II ROM board will be available at $100 for an introductory period only, running through July 31st, at which…

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 produced by plotting adjacent green and violet bars. (Green+Violet=White. ) By plotting only on even bars, (even X coordinates), violet plots can be made. However,…

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 the innocent!). A word of caution: Apple soft programs store in memory just the opposite of Integer Basic, i. e., from the bottom up. Therefore,…

We always look forward to writing this column each month, for a number of reasons.  One is that since it is usually the last new material writtem ,it is this column that gives us an indication of the length of the current issue will run. Secondly, because we look at it as sort of “our own” column we feel free to let our thoughts wander a bit, and we feel this line sometimes will produce some interestbig material. In any…

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 found a second omission in the language; a way to store a non-string variable into a string, the remedy for which is shown as program…

The library is now assembling games and other applications into module form, 2 or three programs on a menu.
