DATA ACCESS CORPORATION V POWERFLEX SERVICES PTY LTD  HCA 99
Data Access is the publisher of the Dataflex software package. Powerflex created the Powerflex software package to complement the Dataflex package. Powerflex was compatible with Dataflex and used certain macros and reserved words used by Dataflex. However the service code for the macros and reserved words was different. It was also accepted by the parties that the object code used by the two programs for the commands and reserved words was not necessarily the same.
Data Access claimed that Powerflex had breached copyright in the reserved words, some macros and a data compression table.
