Simple Tutorial for a WWW Interface
On the Diffraction Group WWW pages you will find a number of examples
of old "command-line" programs using a WWW graphic user interface. It
is often quite easy to make such an interface; here I give a trivial
example taken from a seminar I presented on this subject with Didier Richard.
Why use WWW as an interface ?
1) Programs remain on local computers - easy to update
2) Programs run on any computer - Mac, PC, Unix...
3) User-friendly GUI & on-line help - modernise old pgms.
4) Controlled user access - firewall not necessary.
What programs work with WWW ?
1) Programs that use data files.
2) Programs that use a CLI -Command Line Interface.
3) Programs that use Command Line Parameters
4) Any combination of the above.
What programs DO NOT work with WWW ?
1) Programs that use an INTEGRATED GUI (& no CLI).
2) Spagetti coded CLI - random questions to the user.
........... Because they will not accept packaged input.
