Problem on COBOL source code errors

There are many errors in the following COBOL source code. Identify the errors and rewrite the program so that it contains no errors:
IDENTIFICATION DIVISION   (Full stop required)
PROGRAM ID. ERRORS-EXAMPLE.
DATA DIVISION    (Full stop required)
77 ITEM-DESC PIC X20. [ X(20) required for Picture to define]
77 ITEM COST PIC 999V99. [ITEM-COST required for the Variable Name.]
77 VAT 999V99.  (PIC required for Variable definition)
77 TOTAL PIC 999V99.
PROCEDURE-DIVISION.
BILL-SEQ  (Paragraph names start in Column 8 and require Full stop )
MOVE 0 TO TOTAL.
    INPUT ITEM-DESC  (these 2 are Variables not Files, cannot be in INPUT mode)
    INPUT ITEM-COST.
INPUT-ITER.
    IF ITEM-COST = 0 GOTO INPUT-END  (INPUT-END  not declared)
        ADD ITEM-COST TO TOTAL (must come after ACCEPT Item-cost)
        ACCEPT ITEM-DESC
        ACCEPT ITEM-COST
        GO TO INPUT ITER. (need to use INPUT-ITER paragraph name. )
    VAT = 0.15 X TOTAL (Full stop required and COMPUTE Required for expression)
    ADD VAT TO TOTAL (Full stop required)
    DISPLAY OUTPUT TOTAL (OUTPUT can’t use for variables and Full stop required)
    STOP-RUN. (wrong syntax, it is STOP RUN not STOP-RUN)
BILL-END (STOP RUN is last statement, Bill-end comes before that)
