STRUCTURE:
IF THEN ELSE -all must be on the same line
TRAP1000 - equivalent of ON ERROR GO 1000
DO LOOP - Can be followed by WHILE or UNTIL
EXIT - Terminates Loop
GET KEY -instead of of 10 GET A$:IF A$"" THEN 10
GRAPHICS:
The 264 contains most if not all of the VSP commands you can buy on
cartridge from Commodore for the VIC and the C64, plus some extras
FLASH - flashes strings
COLOUR - sets background, multicolours. etc. AND luminance
GRAPHIC - sets hi-res multicolour or text screen including
combinations, can set hi-res/multi-colour at top plus 5 lines of text
at the bottom
BOX
CIRCLE
PAINT
SCNCLR -same as print chr$(147)
CHAR -CHAR X, Y, "STRING" will print "STRING' at an X,Y position on
the hi-res screen. very handy.
LOCATE -will plot a pixel at X,Y
DRAW -for line drawings, just like VSP
SSHAPE -Save Shape will store a limited area of the screen into a
string variable
GSHAPE - will get a shape from a a specified variable and print it on
the hi-res screen at X,Y
SOUND - single voice, followed by a parameter for a note, tone etc
VOLUME
JOY(N) - needs joystick 1 or 2 and returns a number from 1-8
Machine Language:
The Machine Language Monitor has additions as well some new BASIC
commands to do conversions
DEC - DEC "'FFFF" converts the string to FFFF decimal, variable can
also be used
HEX$ - HEX$(1124) converts a the number 1024 to a string representing
the hexadecimal equivalent. the two complement much like ASC and CHR$
MLM .F- FiII memory from ADDRESS1 to ADDRESS2 with specified HEX value
.H - Hunt Memory
.A - Assemble works like supermon assembler
.D - Disassemble
.M - Memory dump displays memos contents in hex and screen
POKE
characters much like Interrogate in Extramon
.G .X .S. L .R are still the same from other MLM's
Disk Operatting:
The 264 has most common disk commands from BASIC 4 0. For some reason
though the DOPEN command is missing
(The operating system supports more commands than listed here.) |
We'll bring you more information as release version manuals become
available (Ed)
Several new peripherals will accompany the 264 including a letter
quality and dot matrix printer, A new colour monitor, the 1703 is
merely the 1702 in a new black case, but a new faster disk drive, the
SFS 481 another 264 peripheral. The 1531 Datasette is the same unit
with a new plug, useable only on the 264. The 264 Modem is supposed
to be auto answer/auto dial. Rounding out the hardware end of the
computer is a new plotter.
Software compatibility will be a sore spot with new owners of the
264. VIC and 64 cartridges won't work. Most existing programs won't
work either unless they are pure BASIC. The problem lies in the
systems electronic architecture. If you know the difference between
an operating system and an operating table, you may be wondering how
an 8-bit microprocessor can address 64K of RAM. 32K of O/S ROM and an
additional 32K of program ROM. The feat is accomplished with a
sleight of hand called "bank selected memory". The 7501
Microprocessor can only "see" 64K of anything at once, but with
careful memory management, it can switch in (or out) different blocks
of memory so the total of 64K is never exceeded.
The bank selection process is done automatically so you don't have to
worry about it. Long-winded programmers will now be able to write
programs (in BASIC M.I. or both) of up to 64K in length.
The 264 is the first of four New Generation computers due for release
this year. The next one, the 364, was shown at CES but it looks like
it will be summertime before it makes a market appearance. The 364 is
architecturally the same as the 264 but has an extra 19 key numeric
pad, a few more empty sockets inside for software ROMs and built-in
speech with 250 word vocabulary.
Prices and release date are not yet firm, but the 264 should be in the
$400-$600 US range.
Editor's Note
The new C264 and 364 are an interesting progression in the Commodore
evolution. No sprites, no 3 voice sound, yet very powerful. Perhaps
they're leaving that combo for the next step. Whatever the case, the
264 will fill another gap. The added memory, commands and display
features will give a new look so Commodore business software,
especially the luminance control. It's compact, inexpensive, and ROM
software will make it convenient. The Commodore 64 will remain the
superior games machine but the SSHAPE, CSHAPE and the other VSP
commands will produce some handsome graphic control. It almost seems
like Commodore has omitted the advanced graphic and sound capabilities
to avoid instilled anxiety to potential business software writers. I
suppose only time will tell how well they'll get along together as a
family. |
