Not really -- one more level of indirection is involved. He's trying to come up with a way to connect a logical data source/sink in an app with external data. You'd use a file descriptor to do the I/O to the actual data via the task monitor once the source/sink -> data mapping was identified and the task monitor connected it to the application. Other toolsets that have dealt with this concept are Microfocus COBOL, and the open-source GNU Cobol compiler. They went the environment variable and/or config file route. Given that this is a CICS clone, you're likely to be dealing with the same set of people, so don't reinvent the wheel if you don't have to. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
