Pass Perl array to Oracle stored procedure

[Saii]

How can we pass a perl array to stored procedure in Oracle.
The parameter I am using in Oracle is type of table of varchar(500). I am using the system command in perl to execute the procedure

Sample:

system("sqlplus -S $user_det_orcl <<EOF \n "."whenever sqlerror exit failure; \n"."exec  p_test('\@array\');\n"."exit;\n"."EOF\n" );

When I use the above notation, Oracle gives an error about the parameter that parameters types dont match.
Any ideas?
Thanks
