Run the SQL query for the Concurrent Program of your interest.
For example:
SELECT
cp.concurrent_program_name CP_Name, -- The Concurrent Program name
dfcu.end_user_column_name Column_name, -- The real argument name
lv.meaning data_type, -- The data type of argument
ffv.maximum_size, -- The length of the argument
dfcu.required_flag, -- The argument required or not
dfcu.display_flag, -- The argument displayed or not on Oracle Form
dfcu.default_value, -- The default value of the argument
dfcu.column_seq_num -- The argument sequence number
