Carriage return in code
- Thread starter nickree
- Start date
Code:
message "hello~nworld" view-as alert-box.this way lets you insert newlines into strings.
"~n" equals to chr(10), take a look at special characters in the online help (f1).
Code:
put "hello" skip "world".you could also use skip with put, display, or use down frames. hth

Carriage return is the ASCI eqivalent of Char(10),

Carriage Return = CR = Control-M = chr(13)
Line Feed = LF = Control-J = chr(10)
"New Line" = ~n ("~" is the Progress operating system independent syntax for a special character.)
The actual value that a statement such as PUT "~n" will use depends on the operating system in use. For UNIX it is a line feed. For Windows it is a carriage return plus a line feed. On a Mac it is a carriage return (Oops! Progress doesn't run on Macs...
). Check this out for more detail than you could possibly want:

Anyhow...
You say that you are "extracting" some data and want to separate it with what sounds like a new line.
What form are you putting this data in? Are you extracting it to a file or to the screen? Or are you putting into an editor widget?
For most purposes in a Progress program you probably want to use SKIP syntax or, as Joey indicates, a DOWN frame rather than embedding the control character.

turns out theres a little more to it, at least then i first thought.
i wrote a couple short test scripts, heres what came back, using openedge 10.0b gui -
returns length 1 and chr(10)
returns chr(13) and chr(10), and just chr(10) with binary no-convert, i got back the same results using put skip(1).
so, looks like chr(10) is converted to chr(13) and chr(10) when not outputing in binary mode, in windows.
oh, anyways absolutely use skip, or down frame *if you can* inserting "~n" is more of a hack.

Code:
message length( "~n" ) asc( "~n" ) view-as alert-box.
Code:
define var pBuffer as memptr no-undo.
define var str as char no-undo.
define var i as int no-undo.
/* create test file */
output to test.prn /*** binary no-convert */ .
put unformatted "~n".
/* put skip(1). */
output close.
/* read test file */
set-size( pBuffer ) = 1000.
input from test.prn binary no-convert.
import pBuffer.
str = get-string( pBuffer, 1 ).
input close.
set-size( pBuffer ) = 0.
/* display file content */
repeat i = 1 to length( str ):
display i asc( substr( str, i, 1 ) ).
end. /* repeat */so, looks like chr(10) is converted to chr(13) and chr(10) when not outputing in binary mode, in windows.

Try adding chr(10) to the character line value.
Ex. var = "insert line feed" + chr(10) + "second line".
Ex. var = "insert line feed" + chr(10) + "second line".
