The XPA messaging system provides seamless communication between many kinds of Unix programs, including X programs and Tcl/Tk programs. It also provides an easy way for users to communicate with these XPA-enabled programs by executing XPA client commands in the shell or by utilizing such commands in scripts. ... A program becomes an XPA-enabled server by defining named points of public access through which data and commands can be exchanged with other client programs (and users). ...

... Rutherford Appleton Laboratory, Chilton, Didcot, Oxon OX11 0QX, U.K. љ This paper describes how Tcl and the Tk toolkit have been extended to send and receive Adam inter-task messages, and how it has been used to build graphically-oriented user interfaces for various data reduction tasks. ... The user interface uses the message system to control the task. ... adam_init . ... The user interface sends messages to the relay task using the Adam message system, which forwards them to the Adam tasks. ...

The pnet, prun, psrv suite of programs . ... pnet -> prun -> psrv -> disc . ... It can forward commands from pnet to psrv and pass back the replies. prun starts the data taking, gets the data from the spectrometer, and passes it via a socket to the psrv program running on the file server. ... There is a psrv task for each prun task (one for each subband on a spectrometer box). prun starts psrv via xinetd by connecting to the well known port address. psrv accepts commands from pnet via prun. ...

CFITSIO Interface Library CFITSIO is a library of ANSI C routines for reading and writing FITS format data files. ... The CFITSIO library is built on Unix systems by typing: > ./configure [--prefix=/target/installation/path] > make (or 'make shared') > make install (this step is optional) at the operating system prompt. The configure command customizes the Makefile for the particular system, then the `make' command compiles the source files and builds the library. ...

... Although many of the images are used for teacher-driven activities, students do have the opportunity to work with scientists on original research projects. ... The primary goal is to have teachers experience astronomy research and then to bring the research data into their classrooms via the internet. ... They also learn how to process their data, build a solar telescope to take home to their classrooms, and learn background information from astronomers in each of the three research areas. ...
