Application
Hints
Using Entry Assist to Create and Maintain Source Programs
Source programs are typicallymaintained infixed columnformat. Forexample:
NAME
OPERATION
OPERANDS
COMMENTS
To
use
Entry
Assist
to
create
this
format:
1.
Set
the
left
margin
at
the
NAME
column.
2.
Set
tab
stops
at
the
OPERATION, OPERAND,
and
COMMENTS
columns.
Nowyou can
enter
source
statements
without thinking about column locations.
If
you need to continue to another line,
set
the "end of line" signal to provide a
warning
of a
line
ending.
To
create
program prologue sections or other
areas
of continuous comments, the
following
technique
is
useful:
1. Create a group of lines withthe *character in the first and last positions of the
line. (To do this fast,
use
the duplicate line command [" n] with
XEDiT,
and the
Repeat Line Command [Rn] with the SPF editor.)
The
form
on
your
screen
should
look
like
this:
2.
Set
margins
within
the
pair
of *
characters
as
illustrated
below.
The
Less
Than
character
(<)
represents
a left margin. The
Greater
Than
character
(>)
represents
the
right margin. (You do not actually
see
the
<
and
> symbols
except
on
the
scale
line
when
in
Change
Format
mode.)
With word wrap on, you
can
enter
comments
into the lines you
created
without
thinking
about
margins
or
new-line
decisions.
