The VIC-20 and Commodore 64 do not have a built-in MLM, but one can be added. Such a monitor may be either loaded into RAM or plugged in as a cartridge. Monitors may be purchased or obtained from user clubs. Most machine language monitors work in a similar way, and have about the same commands. To proceed, you'll need an MLM in...

Speedscript is a nice wordprocessor. For many, it has proven to be the only wordprocessor they need. It's probably the best thing COMPUTE has ever done.

No Address Implied Mode
Instructions such as I NX increment X , BRK break , and TflY transfer A to Y need no address they make no memory reference and are complete in themselves. Such instructions occupy one byte of memory.

Perhaps the word implied is used in this manner an instruction such as I NX implies the use of the address register and an...

140 Next X
This routine reads the 63 data values and POKEs them into memory. This form of sprite storage requires quite a lot of space. Another less space-consuming method of storage involves writing the sprite data to disk or cassette in a sequential file. By doing this, you can save program memory at the expense of having to read the sprite pattern back from disk or cassette. When first creating a sprite definition file, we still need the DATA statements. With the help of the following program, the...
Global Commander
DataSoft EA 1820 Gateway Dr. San Mateo CA 94404 415-571-7171 I like this nuclear-age political simulation game for the C64 better than Balance of Power for the Amiga.

Global Commander simply has more options, like an SDI system, spy satellites, and a world radio scanner. It also lacks the negative you can't win bias that becomes so tedious when you play Balance of Power....

Chapter Internal Disk Commands
Expert programmers can give commands that directly alter the workings of the 1581, much as skilled programmers can alter the workings of BASIC inside the computer with Peeks, Pokes and Sys calls. It is also possible to write machine language programs that load and run entirely within the 1581, either by writing them into disk memory from the computer, or by loading them directly from diskette into the desired disk memory buffer. This is similar to loading and running machine language programs...

Relative File Storage
Relative file types have the most elaborate internal structure. Relative files are often referred to as random access files. A relative file is actually two files in one 1. A sequential data file with records of a fixed length. 2. A file of track and sector pointers called side sectors. The sequential data file uses fixed length records so that the DOS can calculate where to find any given record. This makes it possible to position to a particular record and read or write it without disturbing...
Differences
If I had to sum it all up in one short statement, I'd say that Butcher approaches image processing from the artist's point of view, but PIXmate treats the whole process like a science. All of Butcher's tools are up front and easily accessible. Chopping, merging, and blending colors is a simple process, as is filtering odd pixels out of a digitized image. There is even a limited DRAW mode toolbox for subtle manual retouching of details. I like it for refining video artwork because it is fast,...
23 Phaser and Siren Sound Effects Using the STEP Command
The STEP statement is a very useful BASIC command in sound effects programming. The STEP command is used in conjunction with a FOR NEXT loop. Normally, a FOR NEXT loop, such as will increment by one each time through the loop. With the addition of the STEP statement, we can increment the counter by whatever value we choose. For example will loop ten times progressing from 5 to 50 by steps of 5. The increment occurs each time the computer encounters the NEXT. With this in mind, take a look at...
