Need to get the input dynamically and write the records

Question

hi everyone,
iam having a doubt in scripts,
1.i need to get the input from user
(input is the table name)
2.if the input matches with the tables in the database and the n it has to write the records in a csv format.
3.the fields should be delimited by comma.
is it possible to write a script or procedure.
the script should be a generic one.
thanks and Regards,

this is the order
but while my output looks like
SQL> set serveroutput on

SQL> set heading off
SQL> spool /emea/dbtest/tamdbin/bnk/bnk.run/DATA.BP/SAM_ACC.csv
SQL> exec input_table('T24_CACCOUNT');
