Throughout the description, all reserved (“key”) words and literals will be surrounded by apostrophes `…'.
Any text beginning from '–' to the end of the current line will be ignored by the parser. Example:

All names appearing in HyperFun program (names of objects, local numeric variables and functions) can consist of letters, digits and underscore character '_' (that is not considered a letter!), but the first character must be a letter.
The text of a program in HyperFun is case-insensitive. So the following pairs of names are equivalent:
HyperEllipsoid and hyperellipsoiD
COS and cos
Xx and xX
