DISK BASIC
You
may
execute
trsdos
commands
directly
from basic by using cmd'T'.
This
is
similar to
cmd"S"
,
except
that
it
lets
you
include a
command
or z-80
program
for
trsdos
to
execute.
As
long as
basic
is
not overwritten
by
the
execution of
the
program
or
command,
control will
return
to
basic; otherwise, control will return to
trsdos.
(trsdos
commands
all
overlay basic;
your
z-80
program
may
not
if
it
loads
above basic.)
Example
CMD"
I"
M
PROGRAM"
returns
you
to
trsdos and executes
the
program
file
program.
CMD'T"
>A$
returns
you
to
trsdos and
executes the
command
contained
in
a$.
CMD'T
Calendar Date Conversion
This
command
converts dates
back and
forth
between two formats: the standard
month,
day, year,
sequence;
and
a year,
day of year,
sequence.
The
content of
the
source
string
determines
which
way
the
conversion goes.
