Clear Screen in SQL*Plus

I'm running the following report but getting an error ``` /* Simple table formatting */ clear screen; accept Report_File char prompt 'Enter a file name for summary report '; /*Set up column headers*/ col StoreCode format A8 heading 'Store Code'; col DESCRIPTION format A8 heading 'Item Description'; col PRICE format $999999.99 heading 'Price'; col QUANTITY format 999 heading 'Quantity'; col (Price*Quantity) format $999999.99 heading 'Value'; /*Format and title pages */ set Pause off; set Feedback off; set Space 6; set newpage 2; set pagesize 54; set linesize 200; set underline =; title center 'Current Stock Value by Store' skip 2 left - 'prepared by Jason Kemeys' &Report_Officer right - &Todays_Date skip4; btitle center format 999 SQL.PNO; /* Set breaks and computes */ break on StoreCode skip 2 on SuppCode skip 1 on Report; compute sum of (Price*Quantity) on StoreCode; compute sum of (Price*Quantity) on Report; /*Select data & send to file*/ spool &Report_File; select StoreCode, Description, Quantity, Price, (Price*Quantity) from Stocks order by StoreCode; spool off; /* Clear all settings */ clear breaks; clear columns; clear computes; set Pause on; ``` Just need to know why its showing the error and how to get it running; first time doing a report in SQL. This is the error I'm getting clear screen; * ERROR at line 2: ORA-00900: invalid SQL statement
