NExS interacts with other applications in two distinctly different ways:
NExS Import and Paste operations let you import data from other programs, such as spreadsheets and tabular text reports. This data is static, meaning that it is inserted into the current NExS spreadsheet but is no longer affected by calculations and manipulations that take place in the source program.
Similarly, you can use Export and paste operations to export static data to other programs. This data can be used by the other program but is no longer affected by calculations and manipulations that take place in NExS.
The most powerful feature of NExS is its ability to handle real-time data transfer with other programs, even those running under different machine architectures, different operating systems - anywhere on the Internet. With this facility, you can have NExS accept, process and display information from other programs in real-time, continually updating the screen as you watch. You can also have NExS transfer data to other programs in real-time.
The Import, Export and Paste operations are used for transferring static data. Dynamic connections are established with special NExS connection routines that you program into the external application. This chapter explains how to use NExS in partnership with other X Windows applications, including how to:
