ON MOVI

In Issue 22 's editorial I indicated that two new GEOS

updater's were scheduled to release soon. While we

haven7heardanythingmoreabout GEOSMegaPatch

\>3.0yet, Wheels 64 hassquealedpast the starting line

and is presently burning up the track. It is indeed a

pleasure toseesuch apowerfulnewsystem releasedat

this point in the history of Commodore computing.

Inside this issue we provide somefirst impressions of

Wheels 64; however, we'll also he revisiting this

subject in afuture issue after looking into technical

aspectsofdriverspeed, compatibilityandotherissues.

Other things you'llfind inside this issue include a

modularprogrammingsystemforthe Commodore 64,

a review of the Centipede BBS program for the

Commodore 128, some tips on dealing with the Y2K

(Year 2000)problem in GEOS, andsome situations to

avoid when programming the 65816.

In addition, there's a rant to programmers about

avoiding the tendancy to become lulled into writing

slow code simply beacuse they have a SuperCPU. I

broke this outfrom the rest because I think it bears an

editorial comment. While I tend to agree with the

opinion putforth on the matter here by JeffJones, I

think that it fails to strongly point out that such

guidelinesneedn'tbefollowedwhen writingprograms

foryourown use. Many BASICprogrammers willfind

that the SuperCPU enables them to create programs

which would have otherwise run loo slow. However, I

do still encourage anyone interested in machine

language to learn it and take advantage of it when

possible—whetheryou have a SuperCPU or not.
