Not quite.  To save or load arbitrary data, you have to use monitor
commands.  Applesoft and Integer BASIC have commands to load or save
BASIC programs on tape: LOAD and SAVE (with no filename argument).  They
might not work under ProDOS, but DOS 3.3 has special code to recognise
the absence of a filename and passing control on to the BASIC
interpreter.

Applesoft also has commands for dealing with copying arrays to/from
tape, and possibly something to do with shape tables.  I don't think
I've ever used them, as I don't remember any details.  Integer BASIC has
some related routines via CALLs, as part of Programmer's Aid #1.

All of these commands are in ROM, so you don't need to boot a disk to
use tape.  There is no way to run a program directly off tape - you have
to load it into memory (LOAD) then run it (RUN).
