19. Work handling 1/2 From ASN.1 to CVS file converter V0.1 documentation: “The General ASN.1 parser generation project can be divided into two subprojects that can be carried out independently providing that the interface between the two modules is clearly defined. The first part or module is a standalone GUI application that takes as an input an ASN.1 grammar and generates a configuration file for the ASN.1 to CSV file converter according to the choices made by the application user. This configuration file is used by the second module – the ASN.1 to CSV file converter that accepts a binary ASN.1 BER encoded file (conformant to the grammar in question) and generates a CSV text file with the values defined in the control file.” 19 DSD 8-11-2008
