This can be very useful
in
Integer
BASIC.
If
there
was a
machine
language
subroutine
located
at
location
64578, a CALL
64578
could
not
be used. This
is
due
to
the
fact
that
the
expression
indicated
is
greater
than
the
largest
integer
that
can be used
in
Integer
BASIC. Using
the
previous
conversion
equation,
the
CALL used
would
be CALL-958.
Example
CALL-936
The
preceding
CALL executes a
machine
language
subroutine
at
the
given
location.
This CALL
is
identical
to
the
HOME
command
in
Applesoft.

will
be
truncated.
