... The only event-driven pieces of software were the user interface Hermes, the display server GIDS and the GDS server. ... Event-driven tasks are fundamentally different from procedural tasks. ... Using this event handling, a collection of routines has been built, which allows the programmer to construct a graphical user interface for a task. ... These are the events associated with user input keywords and one other event which is generated when a task is resumed after it was pausing. ...

Next: Passing Parameters in Up: Monitor and Command Previous: Execution of Commands . The MIDAS command language ( MCL ) consists of all the commands which you enter interactively, and an additional set of commands to provide the necessary tools to write MIDAS ``programs'', called MIDAS procedures . ... The following Command Language commands provide the necessary programming constructs like looping and conditional branching for MIDAS procedures, they cannot be used interactively: . ...

In order to ensure consistency between code written at different institutes, and to ease maintainance and testing, all code shall be written to the following standards wherever possible. ... Proper use should be made of these facilities, rather than coding in the Fortran-77 subset of the language. An explicit interface should be used for all procedures (i.e. subroutines and functions). ... However, general purpose classes should not use the application name (i.e. Sas) as the prefix. ...

... UNIX and Linux don't incorporate the user interface into the kernel; instead, they let it be implemented by user level programs. ... This arrangement makes the system more flexible, but has the disadvantage that it is simple to implement a different user interface for each program, making the system harder to learn. ... X also does not implement a user interface; it only implements a window system, i.e., tools with which a graphical user interface can
