WWW is surely a break-through because of its popularity. Public demand for more attractive websites
and the corresponding investiments for hardware improvement brought forth a superb 'computing' machine as
a by-product.
It has become possible to do a lot of computing works on the server-side for clients.
GCS utilizes this new capablity.
It is desirable that data are provided from a server in the way they can be processed on the client side.
We see a lot of data on the Web that are in the form of either a graph or a table.
Some of them are useless when left alone, as in such cases when those data are coefficients of a polynominal
function.
GCS provides data in the form of a function and the client can process in his C program in whatever the way he
is happy with.
You may have noticed by now that I am not familiar with those convenient tools that appear in the title of
books in the computer bookstore. You guessed right and I confess that I have bought none of those books.
I know vaguely which one appered and disappeared, superseded by another which one, things like that.
It takes a lot of effort to learn and get appreciative on any one such system.
On the other hand, GCS does not invent anything anew. The C programming language has been around for decades
and the CGI using HTML form is very familiar to everyone.
