COMMAND: Allows an externally developed sub-routine to be invoked from BASIC. Use with
caution, not a function for the inexperienced to experiment with. The above
CALL
is relatively
harmless, since it waits for the next frame flyback, which is particularly useful for tidying up the
movement of characters around the screen when producing animation effects.

COMMAND: Causes BASIC to start reading the cassette and to display the names of all files found.
This does not affect the program currently in memory, and so may be used to verify a program that
has just been saved before altering the program memory. The Command asks you to play the
cassette, and on finding a program responds:
FILENAME BlockNumber Flag Ok
Flags indicate the type of recording made:
$
a BASIC program file
%
a Protected BASIC file
*
an ASCII text file
&
a Binary file
Other characters may occur in this column if the file was not produced by BASIC.
