funcs: Browses functions used by algebraic expression language
funcs is a utility which allows you to browse the
functions you can use in STILTS's algebraic expression language.
Invoking the command causes a window to pop up on the display with
two parts. The left hand panel contains a tree-like representation of the
functions available - the top level shows the classes (categories)
into which the functions are divided, and if you open these up
(by double clicking on them) each contains a list of functions and
constants in that class.
If you click on any of these classes or their constituent functions
or constants, a full descritption of what they are and how to
use them will appear in the right hand panel.
The information available from this command is the same as that given in Section 9.5, but the graphical browser may be a more convenient way to view the documentation. There are no parameters.
