Form Feed To Printer

Form Feed To Printer

[jcott]

I am trying to figure out the ascii code so that I can send a
line feed to the printer.

  If anyone knows the Ascii Escape code, or anything else
I can use so that I may send a form feed to the Printer, I would
Appreicate it.

   Thanks,
         Jeff

Don't think of sending a form feed to the printer, that is too low level,
instead just use Text_IO.New_Page, that is what it is for. If it doesn't
work, then your implementation is not doing the right thing.

Linefeed    10   16#0A#
Formfeed    12   16#0C#
CR          13   16#0D#
Escape      27   16#1B#

You can also use the predefined ASCII package...

  Linefeed   ASCII.LF
  Formfeed   ASCII.FF
  CR         ASCII.CR
  Escape     ASCII.ESC

Or since the ASCII package is now obsolete in Ada95 :

	with Ada.Characters;

	Latin_1.LF;
	Latin_1.FF;
	Latin_1.CR;
	Latin_1.ESC;

Pascal.

Pascal Obry suggests using the Latin_1 package instead of Ascii for simple
accesses to control characters.

I think that is a mistake. Ascii is not "obsolete" it is obsolescent, which
means that the designers think it might be considered for removal, but for
the moment if is a first class citizen in Ada 95, and can be used freely.
Personally I think the probability of this package disappearing in the
future is 0.00000000%

The trouble with using Latin_1 is twofold

first it drags in a lot of junk, which is likely to slow down compilation.
by contrast ASCII is right there in standard, no use clause or with clause
required.

second, if you are in a localized environment, say one using Latin-2, then
it may cause torubles to with Latin-1 as well.

This is just personal opinion, my own feeling is that the obsolescent
features annex of Ada 95 is a mistake. Anyway, it is important for people
to realize that all features in this annex are 100% required and 100%
available. It is only a matter of aesthetics as to whether one should use
them. They have been retained because they are used and potentially useful.
You can feel free to use them!
