The following script read all data into arrays (array name is entry name minus @) :
Code:
# Read alle ntries into arrays

entry=GARBAGE
while read record
do
   case "$record" in
      @*) entry=`expr substr "$record" 2 9999` ;;
      *) eval ${entry}[\${#${entry}[*]}]='$record' ;;
   esac
done < input_file

# Display arrays content

for array in DATABASE PACKAGE_SPECS PACKAGE_BODIES PROCEDURES FUNCTIONS TRIGGERS VIEWS SQL_SCRIPTS
do
   eval count=\${#${array}[*]}
   if [ $count -eq 0 ]
   then
      echo "${array} -> Empty"    
   else
      i=0
      while [ $i -lt $count ]
      do
         eval echo \"${array}[${i}]=\${${array}[${i}]}\"
         i=`expr $i + 1`
      done
   fi
done

Inputfile :
Code:
@DATABASE
femotest
@PACKAGE_SPECS
/usr/home/oracle92/sosa/scripts/test.pks
/usr/home/oracle92/sosa/scripts/rep.pks
@PACKAGE_BODIES
/usr/home/oracle92/sosa/scripts/rep.pkb
@PROCEDURES
procedure 1
procedure 2
@FUNCTIONS
function 1
function 2
@TRIGGERS
trigger 1
@VIEWS
view 1
view 2
@SQL_SCRIPTS
sql 1
sql 2
sql 3

Output:
Code:
DATABASE[0]=femotest
PACKAGE_SPECS[0]=/usr/home/oracle92/sosa/scripts/test.pks
PACKAGE_SPECS[1]=/usr/home/oracle92/sosa/scripts/rep.pks
PACKAGE_BODIES[0]=/usr/home/oracle92/sosa/scripts/rep.pkb
PROCEDURES[0]=procedure 1
PROCEDURES[1]=procedure 2
FUNCTIONS[0]=function 1
FUNCTIONS[1]=function 2
TRIGGERS[0]=trigger 1
VIEWS[0]=view 1
VIEWS[1]=view 2
SQL_SCRIPTS[0]=sql 1
SQL_SCRIPTS[1]=sql 2
SQL_SCRIPTS[2]=sql 3

Note: Leading and trailing spaces are not preserved.
If you want to keep them, try :
Code:
while IFS='' read record

locale::codes::script

Locale::Codes::Script(3)				User Contributed Perl Documentation				  Locale::Codes::Script(3)

NAME

       Locale::Codes::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Codes::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::Codes::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. 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:

	  $script = code2script('phnx','alpha');
	  $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_SCRIPT_ALPHA
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.  It also includes additions to this set
	   included in the IANA language registry.

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

	   This is the default code set.

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

ROUTINES

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