Problem with sort-of array in SH
Hello to everyone!

I'm really new in shell scripting and I'm experiencing a very odd problem. This is my first post in this forum, hope you can help!

I know that declaring arrays in Bourne Shell is impossible. But this is where I start having problems - system administrator did not install ksh. So after searching some in google, I found an alternative way to declare an array, however I do not know if this is gonna work.

Code:
for i in $*
do
for word in $i
do
echo "$word"
done
done

It reads values from command line and prints them out. I need characters entered in command line to be printed out in one line without spaces and I've done it by myself too:

Code:
echo "Formatted text:"
for var in $*
do
printf "%s$var"
done > "text"
cat text

But what about arrays? Would this work for me? (Found it by googling):

Code:
echo "Enter the line: \c"
read temp
n=0
for word in $temp
do
n=`expr $n + 1`
   eval part$n="$word"
done

All I could achieve was printing out the number of $n which was storing information. Creating another loop below this code trying to take values from part$n or $part$n did not give any results:

Code:
for var in $part$n
do
printf "%s$var"
done

Also, what exactly 'expr' and 'eval' stands for?

Any help would be appreciated,

locale::codes::langext

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
