For this one, you may rephrase
LOOKUP credit_card_number IN credit_card_info STORE
IF credit_card_number.CREDIT IS GOOD   //SPECIFY WHAT CREDIT YOU REFER TO

IF sub_total < limit_amount
      SET new_balance=last_blance + subtotal 
   ELSE
      DISPLAY over_limt_error ON SCREEN
   ENDIF
ELSE
   DISPLY bad_credit_error ON SCREEN     
ENDIF   






Process 1.3
Process credit card

SET sub_total = 0
FOR transaction WHERE transaction_id = current_ transaction
LOOKUP item_id in local_inventory STORE
Sub_total = Sub total + item_listed_price * quantity
ENDFOR
LOOKUP credit_card_number IN credit_card_info STORE
IF good_credit = true
   IF sub_total < limit_amount
      SET new_balance=last_blance + subtotal 
   ELSE
      DISPLAY over_limt_error ON SCREEN
   ENDIF
ELSE
   DISPLY bad_credit_error ON SCREEN     
ENDIF

Robert,

It would be nice if you can show a process specification for the lower level 
process, since all these are only 2nd level processes. Are they already the 
primitive processes and your group will not be expanding them? Process 
specifications are for primitive processes only.

Also You may also need to define the terminologies you used in the process 
specifications in your data dictionary.

For example, the following is fine if process 1.1 is the primitive process and 
you will not expand it further. However, you may need to make sure entries 
like transaction_id, item_unit_price, and return_amount are all defined in the 
data dictionary. 

Process 1.1
Process refund

SET return_amount = 0
LOOKUP transaction_id IN trasaction STORE
FOR each item
   ACCEPT item_id FROM cashier
   ACCEPT reason_of_returning FROM cashier 
   ACCEPT accept_return FROM cashier
   IF accept_return = true
      READ item_unit_price from purchased_item STORE
      SET return_amount = return_amount + item_unit_price
      SET item_returned_day = today
   ENDIF
ENDFOR

Have a nice week and see you tomorrow.

Your instructor,
Brenda
