Program Overview

       Before this program is used it is imperative that the sorted file used has been produced by the Sort program (494792P2.exe), and prior to this has been validated by the validation program (494792P1.exe). If this is not the case then the outcome of this program is not guaranteed to be in anyway reliable or useable, and the Customer Master file created can not be trusted in any shape or form.

       The sorted transaction file from the Sort Program (494792P2.exe) is used to update a Customer Master file, and create a new generation of that master file. Reference is made to an indexed sequential Stock master file for pricing information. Transactions that can not be actioned are reported on the printer under suitable headings with an appropriate error message.

       The text file which contains the sorted transaction records must be named 494792SD.DAT, the customer master file must be named CUSTMAST.DAT, and both must be located in the same directory from where the update program is located and executed from. The new customer master that is created will be named 494792VF.DAT, and will be located within the same directory as where the program was executed from. This is unless the user changes these default file names by entering additional program parameters at the command line. Below describes how the default file names can be overridden: -

       494792P3.exe <sorted file> <customer file> <new customer file> <printer>

       The defaults file names are as follows: -

              Sorted file - 494792SD.DAT
              Customer file - CUSTMAST.DAT
              New Customer file - 494792NF.DAT
              Printer - PRN

       If the user wishes to override one of these files they must also enter the file names of all the files preceding it. For example to override the printer to a text file named test.txt, they must enter the following command: -

       494792P3.exe 494792SD.DAT CUSTMAST.DAT 494792NF.DAT test.txt

       However if the user only wishes to change the name of the sorted file, they may enter the following command: -

       494792P2.exe SORTED.DAT

       The overriding of the default file names is mainly for test purposes or where there is a need to do so. Such a need may arise when there is a need update an old master file with some old data, which maybe required to reprint a report. The everyday users of this program need not even have to be aware of this overriding feature.
