Chapter 11
To load saved information back at a later date, the tape le that has been written to
must be attached in Media select. For example, attach the le test_WR created above,
return to The Spectrum BASIC prompt, and run the following:
NEW
LOAD “”
Once The Spectrum has reset and you have entered the LOAD command, you will
see The Spectrum display the following text
Program: test
and the usual 0 OK, 0:1 completion message at the bottom of the screen. Typing LIST
will show the program you previously saved:
10 PRINT “Test”
The saving of BASIC programs is often followed by the saving of arrays and bytes.
For example:
DIM b(2,3)
SAVE “array” DATA b()
The contents of the data array b array will be saved to USB stick by being appended to
the end of the writable tape le currently in use, which in this case is the le created by
saving the BASIC program. This behaviour supports the common use case of having
a BASIC program rst on a tape, followed by all the data it needs stored sequentially
as separate les on the same cassette tape.
In general, saving a BASIC program will dene the .TAP lename used for subsequent
SAVE commands.
To illustrate this dynamic naming of les on USB stick, press HOME and enter Media
select. Now eject the currently attached tape le by pressing F, and then return to
The Spectrum BASIC.
Save the test program again using the same lename as before:
SAVE “test”
Conrm that this has been written to USB stick by pressing HOME and entering Media
select. You will see the le test_WR listed as before, in addition to a new le named
test-1_WR.
