load
with
the
r
option
is
equivalent
to
the
command run
exp$,R. Either of
these
commands
can be used
inside
programs
to
allow
program
chaining
—
one
program
calling another, etc.
Example
L0AD"PR0Gi/BAS:2"
Clears resident
basic
program and
loads
progi/bas from Drive

merge
is
similar to
load
—
except
that
the resident
program
is
not erased before
the
new program exp$
is
loaded. Instead, the
new
program
is
merged
into the
resident
program.
That
is,
program
lines in
exp$
will
simply be
inserted into the resident
program
in
sequential order.
If
line
numbers
in
exp$ coincide with
line
numbers
in
the
resident
program, the resident lines will
be replaced by those
from
exp$.
