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

If you want to keep them, try :
Code:
while IFS='' read record
