Testing a Program
The
operating
system
provides
you
with
facilities
to
test
your
program
from
the
terminal.
They
are
the
test
facilities,
if
any,
provided
by
your
compiler,
~nd
the
TSO
TEST command.
The
compiler
test
faciliti~
are
described
in
the
publications
associated
with
the
compiler.
A
brief
description
of
the
TEST command
follows.
The TEST command
allows
you
to
"debug"
your
program.
That
is,
it
helps
you
to
test
a
program
for
proper
execution
and
to
find
programming
errors.
To
use
TEST
effectively,
you
should
be
familiar
with
the
assembler
language.
If
you
are
using
another
language,
for
example
COBOL,
you
can
still
use
the
TEST command
to
obtain
listings
and
other
information
to
give
to
your
installation's
system
programmer
who
can
help
you
debug
your
program.
(You
can
use
the
full
facilities
of
the
TEST command
to
debug
your
program
if
you
can
correlate
the
statements
in
your
source
program
listing
to
the
resultant
assembler
language
statements
in
the
object
listing.)
If
you
are
an
assembler
language
programmer,
refer
to
the
publications"
TSO
Guide
to
Writing
a
Terminal
Monitor
Program
or
a
Command
Processor
and
Command
Language
Reference
for
a
complete
description
of
the
facilities
of
the
TEST
command.
If
you
are
not
an
assembler
language
programmer,
your
system
programmer
will
probably
provide
you
with
a·
test
procedure.
The
most
common
situation
he
may
provide
for
occurs
when
your
program
is
executing
and
you
receive
a
message
that
the
program
has
abnormally
terminated,.
He
may
tell
you
to
enter
the
TEST command
and
then
the
LOAD
subcommand
with
the
name
of
a
program
that
will
test
your
program.
For
example,
if
the
name
of
the
program
that
will
test
yours
is
DPTEST,
use
the
following
sequence,.
READY
test
TEST
load
(dptest)
If
the
system
programmer
does
not
give
you
the
name
of
a
testing
program,
he
may
instruct
you
to
use
the
TEST command
and
a
set
of
its
subcommands
that
produce
listings
of
your
program
and
other
pertinent
information.
For
example,
he
could
ask
you
to
perform
procedures
similar
to
the
following,.
