TRSDOS
Note:
System
diskettes
contain
some
files
which
are
not
shown
in
any
of the
directory listings.
You
may
delete these
files
with a special
form of purge:
mm*
:d (file-type)
The
asterisk
tells
trsdos
to
ask
you
if
you want
to
delete the
System
files.
If
you do
delete
them, the diskette
becomes
a data diskette
and
may
only be used
in
Drive
1,
2
or
3.
The
other
parts
of
this
command
are as
explained previously.
However,
be sure
to
do
the
purge
using Drive
1,
2 or
3,
since the diskette will
become
'
'non-
system'
'
during the
purge.
RELO
Change
Where Program
Loads
into
Memory
file is
the
file
specification,
the user

of

This
command
allows
you
to
change
the
address
at
which
the
program
loads into
memory.
It
does not
change
the
program
itself.
Note: This
command may
be useful
in
conjunction with
dump.
Example

load the

program/cmd
at
the
new memory
address
of 6578.
