Commodore VIC-20 - Page 25

LOAD +1*"p 8 LOADs first program from disk.
LOAD "AB*'\ 8 Loads first program beginning with AB.
LOAD L1HELLO"r S Looks for a program on device 8 (disk
drive},
LOAD "71,1 Looks for the first program on tape, and
LOADs it into the same part of memory that
it came from.
10 LOAD"NEXT'\ 8 Finds the program called NEXT on device
8, LOADs, then RUNs it.
Because of possible problems with old tapes or misaligned
recorders, it is possible that the program will not LOAD correctly.
The VIC stores two copies of the program on the tape. If they don't
match, the message LOAD ERROR is displayed. The program may
LIST correctly, but probably won't. In any case, there is most likely
some problem, some section of memory that is not right, and the
program should be re-LOADed. It is wise to make an extra copy of
any program, in case you run into this problem at some time.
In the case o1 a very bad LOAD, some of the important memory
locations inside the VIC may be changed. If you get weird results
after a LOAD, like the VIC not understanding normal BASIC
commands anymore, you'll have to turn the VIC off and then on
again.
NEW

NEW None None
NEW is used to tell the VIC to erase a current program from
memory so a different program can be used. Unless the program is
stored (on tape or disk), ft will be lost unless it is typed in again from
the beginning. For this reason, you should BE CAREFUL when
using this command! Not clearing out an old program before typing
in a new one can result in a confusing mixing of the two programs.
NEW can also be used as a statement within a program. When
this instruction is executed, the program in memory Is erased, and
the program stops. This is not a good programming technique,
especially if you RUN the program and it erases itself while you're
writing or debugging it.
EXAMPLE:
NEW Clears the program & variables.
10 NEW Performs the NEW operation and stops the program.
