Data Acceptance to Printout.

[scurf]

Good evening chaps and chapesses,

I need to code a program that will read a file from disk called "SALES-FILE.DAT" , the data is already in ascending order of TYPE-CODE and pre-validated and will eventually be sent to the printer.. I am having my usual problem of drawing a structure chart, I have this so far.

______________ SALES PROGRAM____________
| | |
INITIAL UPDATE PROCESS CLOSE
____PROCESS______ UNTIL END OF FILE FILES
| | |
OPEN READ PRINT
SALES SALES HEADINGS

1) Should my update process be on a separate chart?

The main process required is to Read the field TYPE-CODE of the incoming DATA which is either a "1" or a "2", I need to code a control break when the TYPE-CODE changes from 1 to 2,.
If 1 is read then the field UNIT-PRICE (pic 9(3)v1) needs to be multiplied by the field WEIGHT, When 2 is read then the field UNIT-PRICE needs to be multiplied by the field QUANTITY.

This is only a small part of the program requirement, any help on the structure chart would be great, I am sure that I can code most of the other requirements of the program, but any help would be greatly appreciated.

Cheers all
