Copy A$ to d$&B$
This computes the difference
between
the
number
of
bytes
of
memory
available in bank B and
the
number
bytes in the
program
Tank.
(c will
be
smaller
than
that
which
you
would obtain using
the
file
length
from the CAT command.)
This is the new program name, for ex-
ample, Vol.
This renames the Tank program Vol and
copies it into bank B.
The
program
should have different
names
in
the
HP-75 and the PMS or
confusion
will
result when you attempt
to
run
it.

resident
in
the
PMS under the name Vol.

This procedure may be repeated
until
the PMS bank is full.
You now wish to convert your file to a ROM file.
Copy 'all:romb' to 'Volume'
This copies the
entire
contents
of
the B bank into the HP-75 where it is
named Volume.
It is now designated a
ROM file which means it
can
not
be
edited; only copied or purged.
You now notice the misspelling in line 20 of your program.
If you have not already purged bank B, you may copy the Vol
file
the
HP-75, make your corrections, and return the file to bank B.
the Volume ROM file from the HP-75 and copy in a new
Volume
ROM
bank B.
If you have already purged bank B, proceed as follows:
Purge bank A of all files if no other empty bank is available.
