30. Program verify
    ~~~~~~~~~~~~~~
To see if a BASIC program has been successfully SAVEd to tape, without losing
the current program from memory, type *LOAD "" 8000 <Return>, (note the empty
quotes). This works well for programs of not more than 16k in length, as it
is simply trying to 'write' into the BASIC ROM, which it cannot do. However,
all the normal error-checking of the tape data takes place, accompanied by
the usual "Searching" and "Loading" messages. If you have sideways RAM, then
you should operate the write-protect switch to avoid garbage being written
into the RAM.
