Another
limitation is
due
to
the
differences
in
the
internal
representation
of
num-
bers. Transferring
data
files
may
result
in
numeric overflow or
underflow
conditions or
in
changes
in
precision.
In
the
overflow
junderflow
condition,
the
utility replaces all
overflow
or
underflow
values
with
the
maximum
or mini-
mum
values
(I
t·~
F
and
E P
~:;)
available
on
the
Integral PC.
When
the
number
to be transferred
cannot
be
represented
by
a
binary
number, there will be a
change
in
precision. Integer
values will
be
transferred
with
no
loss
in
precision.
Files
Containing
Non-displayable
Characters.
With
the
default character
font
on
the
Intergral Personal Computer,
characters
with
the
ASCII decimal codes
in
the
ranges 0
through
31
and
128
through
159 are non-displayable charac-
ters.
When
a
program
file is transferred to a
HP
-
UX
ASCII
file,
any
non-displayable characters are escaped
with
a
II
,
...
/
followed
by
the
character's three decimal digit ASCII code.
(The
"~"
is
represented
on
the
screen as
II
~
~".)
Because this substitution expands lines
of
code
in
Series 80
BASIC,
the
resulting lines
may
be
too long to
use
with
the
GET
command.
In
this case
the
user
will
need
to
edit
the
ASCII text file.
Once
the
parser
has
accepted
the
line
contain-
ing
the
non-printing
characters,
the
4-character sequence is
stored as a
I-byte
ASCII character.
The
upload
program
accepts
both
single-
and
double-sided
micro flexible discs. The
internal
disc drive
in
the
Integral PC
will
not
accept early versions of
the
single-sided disc
that
do
not
have
the
spring-loaded
shutters
(used
with
HP
9121 sin-
gle-sided disc drive).
If
your souce disc
cannot
be
inserted
into
the
internal
drive, copy
the
disc
on
your Series 80 com-
puter
to a single-sided disc
with
a
spring-loaded
shutter.
