AWK: Backslash \ and forcing output not to go onto new lines
Dear all,
I am using Mac OSX, have been successfully written an awk script during the last days. I use the script to convert parts of a .dot-file into graphml code.

First question: Backslash
My .dot-code includes repeatedly the sign "\n".

I would like to search for this sign and substitute it.
This does not provide the effect:

Code:
if(labelstring~/:\\n/) { 
                print "Old: " labelstring;  
                sub("\\\n", " ", labelstring);
                print "New: " labelstring;
            }

I get as a result:
Code:
Old: find?:\n2>assumption>contents_vs_form 
New: find?:\n2>assumption>contents_vs_form

Neither does it work if I write
Code:
sub("\\n", " ", labelstring);

.
(Substituting "assumption" works without problems.)

Do you have any hint of how to get the sign "\n" substituted?

Second question: forcing output not to go onto new lines
I wonder if a simple way exists to tell awk to put a number of outputs onto the same line:
awk reads in from asource file a line word by word. i want to print some words, alter some and then print them, and again simply print some together with some additional information of mine ("info").

Code:
do
        {    
            labelword_cleaned = $labelword;
            sub("\",", " ", labelword_cleaned);
            if(labelword_cleaned~/:\\n/) { 
                print "Old: " labelword_cleaned;  sub("\\\n", " ", labelword_cleaned);
                print "New: " labelword_cleaned;
            }
            print labelword_cleaned 
            if($labelword~/\"/) { 
            # This bit of code brings us out of here if we encounter an '"'.
            break};
            ++labelword;
        } while(labelword<80);

This operation acts on up to 80 words of a line. i want the out put (i.e. cleaned up words) to go on one line, without any linebreaks.

Do you have any hints for me?
cheers,
Ingli

locale::script

Locale::Script(3perl)					 Perl Programmers Reference Guide				     Locale::Script(3perl)

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. The ones currently supported are:

       alpha
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       numeric
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Script::delete_script  ( CODE [,CODESET] )
       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
