where can I get the 3Dginput function that is mentioned in some of the posts??
There is no function named 3Dginput, just ginput without the 3D.
The reason you have seen 3Dginput is that Google Groups does MIME quoted-printable
encoding of characters outside the range of printable US-ASCII. For example,
capital A with the grave accent (`) is character number 192, which is hex C0,
the encoding for which is equal-sign Cee zero . So if someone happens to post
that character from google groups, you would see =C0 in the posting. But in
order for this encoding scheme to work, there has to be a way to represent
the equal-sign itself. equal-sign is character 61, hex 3D, so everywhere
there was a -real- equal-sign in a posting, google groups replaces it with
equal-sign three Dee, =3D so that it can then use the equal-sign everywhere
else to signal an encoded character. If the original text happened to include
equal-sign ginput as in coords=ginput(2); then google groups would encode
the equal-sign as =3D, resulting in coords=3Dginput(2);
It's a lousy encoding scheme for computer programming languages or mathematical equations, but it is an international standard. Really,
though, Google Groups should not be using it for anything sent to Usenet,
as Usenet standard predate the scheme... but trying to get Google to budge
on anything like this is -nearly- hopeless.
