search online help system
? key
?? key
where key is a literal string (without quotes)

The
?
operator is used to search the online help system for
information matching a keyword.
The command has the form
?key
where
key is a string without quotes.
The
?
operator is case insensitive and ignores blank space before or
after
key. Also, the semicolon usually required at the end of a line of
CoCoA input is optional. The
?
operator was introduced in CoCoA 4.2.
The online help comprises a descriptive page for each CoCoA command/function.
Each page summarises the syntax, gives a short verbal description, and some
examples of use. Often there are also references to other closely related
command/functions.
The search system is fairly simple. The searching algorithm looks through
the title and keywords of each manual page. If the given
key appears
as a (case-insensitive) substring of the title/keywords of just one manual
page, or if it matches exactly then that page is displayed. In any case the
titles of all other pages where a match was found are printed in "menu" style.
