EXAMPLE:
10 NEXT X: REM THIS LINE IS UNNECESSARY
RESTORE RESTORE i//ne#l
When executed in a program, the pointer to the item in a DATA statement
which is to be read next is reset to the first item in the list- This gives you
the ability to re-READ the information. If a [line #] follows the RESTORE
statement, the pointer is set to that line. Otherwise the pointer is reset to
the first DATA statement in the program.
EXAMPLE:
RESTORE 200
RESUME RESUME l//ne # /NEXT |
Used to return to execution after TRAPping an error. With no argu
ments, RESUME attempts to re-execute the line in which the error
occurred. RESUME NEXT resumes execution at the next statement
following the statement containing the error; RESUME line # will
GOTO the specific line and begin execution there.
RETURN return
This statement is always used with the GOSUB statement. When the
program encounters a RETURN statement, it goes to the statement
immediately following the last GOSUB command executed. If no
GOSUB was previously issued, then a RETURN WITHOUT GOSUB
ERROR message is delivered, and program execution is stopped.
SCALE SCALE <7/0>
The scaling of the bit maps in multicolor and high resolution modes can
be changed with the SCALE command. Entering:
SCALE 1
turns scaling on. Coordinates may then be scaled from 0 to 1023 in
both X and Y rather than the normal scale values, which are:
