Load the next program found into memory. If vou
start a LOAD when the cassette
is
in the middle of a
program. the
PET
will
read
pa
st the remainder of the
current program, then load the next program.
Search for the program named
EGOR
on the tape
cassette. and load it
into
memory.
Search for the program named WHEE!LS on the tape
cassette. and load it into memory.
Where a program named X
is
not
on the tape. this
command
will
produce a list of ail the programs on
the tape in the form:
FOUND program 1
FOUND program 2
etc.
LOAD "EGOR"
N$="WHEE!LS"
LOAD N$
LOAD
"X"
After
the first program has been loaded fram a tape. vou can for conven-
ience leave the PLAY key depressed if vou
will
be
loading again from the tape.
However. do not leave the PLAY key depressed if vou
will
subsequently
be
saving
a program.
PET
can sense
that
a tape control key
is
depressed.
but
it cannat dis-
tinguish between them. A common error
is
ta
LOAD, then subsequently
attempt
ta SAVE,
with
only the PLAY key depressed.
Examples:
LOAD
Sometimes vou may have trouble loading a program from tape into memory.
Often the
PET
will
find the program name
but
does not load the pragram correctly
or does not load it at ail.
If
this happens. the only thing vou can do
is
to
try
ta
load
the pragram again. Rewind the tape and reload (several times if necessary). If this
does not work. there may have been a problem
when
saving the program (SAVE
command) or in the cassette
unit
itself.
LOAD
in
Program
Mode
When
the LOAD command
is
executed in program mode. any listing of
LOAD messages
is
suppressed unless the tape PLAY key
is
up (off).
When
the
PLAY key
is
off. the
following
message
is
shawn so
that
the load can proceed:
PRESS
PLAY
ON
TAPE
#1
OK
' when PLAY
is
depressed
LOAD in program mode can
be
used
ta
build program overlays. A LOAD
command executed from a program causes
that
pragram's execution ta stop and
another program to
be
loaded. overlaying the program currently in memory
that
issued the LOAD request. In this case the
PET
does
not
perform a
CLA.
thereby
allowing the first program
ta
pass on ail of its variable values ta the program being
loaded. The overlay program, and ail subsequent overlay programs, cannat
be
larger than the first program in the overlay series.
