Hi,

In Java you can use "\n" as a symbol for a new line in a text string.
How do you this in rexx ?

I do it like this :

text = "This is line 1"d2c(10)"This is line 2"
say text

Can I do this in a simpler and nicer way ?

Thanks,

�smund

  REXX (and Object REXX) hasn't scape sequences.

  eol = d2c(10) /* or eol = '0a'x */
  text = "This is line 1" || eol || "This is line 2"
  say text

  Also you can make a special function for this purpose (and you can
add other scape sequences like \t):

  text = scape("This is line 1\nThis is line 2")
  say text
  exit

  scape: procedure
    return changestr('\n', arg(1), '0a'x)

  This is valid only for UNIX-like (Linux, BeOS...) systems: eol =
'0a'x (linefeed). In Mac systems: eol = '0d'x (carriage return). In
DOS-like systems (DOS, Windows, OS/2): eol = '0d0a'x. (The scape
sequence "\n" can be one of this options.)
  In Object REXX there are another way, but this is other story.

As Salvador suggests you can do this more tidily, but perhaps you should 
look at why you want to do this in the first place. If you are building 
multi-line output for single say later, perhaps you should do one of the 
following instead:

a) Use say on each piece, e.g.

say "This is line 1"
say "This is line 2"

b) Build a stem and say them later, e.g.

text.1 = "This is line 1"
text.2 = "This is line 2"
text.0 = 2

....

do i = 1 to text.0
   say text.i
end

Both of these have the advantage of being "nicer" and platform 
independant too. Also, both these techniques will work if you write a 
stream using the lineout function instead of using say.

(Or, to put it another way, don't try to write Java in REXX!)

Please note, that REXX provides automatic concatenation of strings.
IMO, the following equivalent line is much better readable:

   text = "This is line 1"eol"This is line 2"

or as an alternative, what I prefer the most:

   text = ''
   text = text"This is line 1"eol
   text = text"This is line 2"

  Yes, I know it. :)

  I prefer one method or other depending on the day of the week. ;)

  Curiously, PPWizard has problems with implicit concatenation and
Dennis recommends explicit concatenation in REXX code of PPWizard
macros.

   What about the following alternative?

      text = '' ||,
                "This is line 1"eol ||,
                "This is line 2"

Anyone know if the Arexx BIF will do '\r', etc. as they did on the Amiga?

     Yes.  Here we're getting into preferences because both are
correct.

     My preference is Salvador's origninal:
> text = "This is line 1" || eol || "This is line 2"

     When I see text on both sides of a quote mark, it takes time
to parse out (mentally) which is being quoted and which is outside
the quotes.  Using concatenation marks makes it obvious.  I do use
the automatic concatenation when I want the automatic space
between.

     Speaking of style, though, I've begun to use single quotes
instead of double.  That way, my programs can be fairly
consistent, even when I need to include the double-quotes that
delimit filenames which contain spaces.
