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::langfam

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

NAME

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

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. 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 = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
