then type in the following from the keyboard.
SAVE 11 CALCULATION "
J
Here, "CALCULATION" is the name which is to be recorded on the cassette tape to identify the
program. Any name may be assigned, but the name connot be longer than 16 characters.
Note: The
J
symbol in the example above represents the
I
CR[ key.
When the[ CR[key is pressed," .!. RECORD. PLAY" is displayed on the screen. Pressing the
I
RECORD
button on the data recorder at this time records the program on cassette tape.
The name which is assigned to the program is referred to as its file name. Specification of a file name is
not absolutely necessary, but from the point of view of file management it is a good idea to assign one.
Of course, the file name is recorded on the tape together with the program.
When recording is completed, READY is displayed to indicate that the computer is finished. Now press
the STOP button on the data recorder and rewind the tape.
The program is still present in the computer's memory after recording is completed, so type in NEW
J
to delete it (enter LIST J to confirm that the program has been deleted). Now let's try using the LOAD
instruction to load the program back into memory from the cassette tape as described on page 14.
When a cassette tape contains many programs, that which is to be loaded can be identified by specifying
the program's file name together with the LOAD instruction as follows.
LOAD
11
CALCULATION 11
J
Specifying the file name in this manner tells the computer to ignore all programs on the tape other than
that with the specified name. If the file name is not specified (if only LOADJ is entered), the computer
loads the first program encountered.
Note: When using cassette recorder other than the data recorder built into the MZ-731, and MZ-721 read
the instructions on page 109 before attempting to record or load programs.
The LIST command shown above can be used in a variety of different ways. For example, during
editing LIST 20
J
can be used to display just line 20 of a program. The entire program can be listed
by entering LIST
J .
Other uses of the instruction are as follows.
[[J[IJ[BJITJ EJ[a][QJICRI
[[J[IJ[BJITJ [a][QJEJI C RI
[[J[I][BJITJ [a][QJEJ[QJ[Q] I
c
RI
[[J[I][BJITJ [a][QJ IC RI
Lists all lines of the program to line 30.
Lists all lines from line 30 to the end of the program.
Lists all lines from line 30 to line 50.
Lists line 30.
When editing programs by listing individual lines with the LIST instruction, press the
I
CLR
I
key (the
INST
I
key) together with the
I
SHIFT
I
key when the screen becomes distractingly crowded. This
clears the entire screen and moves the cursor to its upper left corner. (This does not affect the program
in memory). Afterwards,
enter LIST< line number>
J
again to list the line which is to be edited.
