Beat the spread with your Apple by DAVID COWLES and BILL MARQUARDT II Computing MagazineOCTOBER / NOVEMBER 1985Works with DOS 3.3 and ProDOS When the Miami Dolphins met the San Francisco 49’ers in the Superbowl last January, the “Vegas line” favored the Niners by three points. This “spread” meant that an even-money bettor on the Dolphins would still win unless Miami were beaten by four points or more. Would you have taken that action? On which side? Football Prognosticator picked…

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 to conform to the Applesoft format. This means that the Integer commands that are not compatible with Applesoft must be changed.  For example:  TAB must…

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 switch is in the down position, APPLESOFT will be selected.  In addition, it is not necessary to change the switch position to call the non-default…

The big news story of this issue is obviously the arrival in town of Disk II and Applesoft II ROM. Rather than do a review, we have hidden behind the pretext of an editorial to state our feelings on the failings of Disk II and A/S ROM.  I’ve got a feeling I’m failing? (Oh dear! )) Applesoft II ROM for $100 is like buying 10K of memory for less than half price, since it frees that amount of RAM for…

Documentation has been cited by Apple Computer as a cause of delay in shipping both the new ROM board and the Disk II. Discs have been rescheduled for shipping during the first week of July, while the Applesoft ROMs should follow within two or three weeks. Well worth waiting for!

Here is a patch to correct one of the few bugs found in Applesoft II. The HTAB function will space 2 places further to the right than intended unless corrected with this patch: POKE (HM-28), 202 where HM = the value of HIMEM: for your Apple. This should be done after loading & prior to running.

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 RETURN 410 POP:PRINT “FOR NEW PAGE HIT ANY KEY”:CALL 756:GOTO 000 Line 400 reads the cursor and finds whereitis on the page.

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 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…

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 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 also be a HIRES Ascii character set, displayable concurrently with the graphics. The Applesoft Rom board is scheduled for release to dealers July I st…

As stated elsewhere in this issue, Apple Computer plans a new edition of Applesoft on tape about six weeks hence. They have requested that users advise them as soon as possible of any bugs they have encountered. This goes for Integer Basic, as well. This is a project in which EVERYONE can contribute. LET’S DO IT NOW, at this coming meeting. Make a list out, as soon as you read this, any basic bugs you are aware of, and bring…

The following recipe will save you loading time on your Applesoft programs. 1. Load Applesoft 2. Do not “RUN” it. 3. Using the DEL command, delete lines 0,940, inclusiv. 4. Enter this line: 950 POKE 18,255 This will give you a preset version of Option 1, Applesoft graphics mode. 5. “SAVE” this at the beginning of a blank cassette and follow it with saves of programs written in Option 1. For Option 2, do the same except make line 950…
