Passing unix variable value to plsql block

Question

hi..
i want to pass the value of a unix variable to a pl/sql block. I dont know how to go about it.
My code is
for all the files in the directory, ( say $i as the file name )
sqlplus -s <<!
cmdp_rdev/cmdp_rdev@cmdp
declare
no number:= 0;
BEGIN
no := run_owb_mapping('CMDP_RDEV','LOC_PROC_FLOW','PROCESS','PROCESS_HOTEL_DATA',CUSTOM_PARAMS='FILE_NAME=$i');
end;
In the above example, i want the file name ( if x.txt ) to be passed to the procedure call as :
no := run_owb_mapping('CMDP_RDEV','LOC_PROC_FLOW','PROCESS','PROCESS_HOTEL_DATA',CUSTOM_PARAMS='FILE_NAME=x.txt');
How do i do this..
thanx in advance

thank you for the reply..
well that will not work.. since values concatenated to strings cannot be passed as parameters.
for the file Oct_2005.csv, the following was the output
no := run_owb_mapping('CMDP_RDEV','LOC_PROC_FLOW','PROCESS','PROCESS_HOTEL_DATA'
,p_custom_params=>'FILE_NAME='''||Oct_2005.csv||'');
ERROR at line 4:
ORA-06550: line 4, column 115:
PLS-00201: identifier 'OCT_2005.CSV' must be declared
ORA-06550: line 4, column 1:
PL/SQL: Statement ignored
