Ok
I
This
is
not the program that was saved on the cassette (line 30
is
missing). The
CLOAD? command will
be
used
to
compare the program in working memory
to
the
program saved on cassette. Since they are not the same, an error message will be
displayed.
Rewind the cassette and press the play key. Enter the command
CLOAD?
This time, the message:
Verify
failed
will be displayed, indicating that the two programs are not the same.
Don't forget the question mark (?) after CLOAD since otherwise the program saved on
tape will
be
loaded into working memory, replacing the resident program there.
If
the
CLOAD? command indicates a
"bad"
program on tape. then the CSAVE command
can be used again to resave it.
