Keyword
In
computer science, a
keyword is an
identifier which has been reserved for
core language usage. Some common keywords are:
else,
end,
goto,
if,
print,
return,
switch,
then,
while, etc. There are usually restrictions about reusing keywords as names for user-defined objects such as
variables or
procedures. Languages vary as to what is provided as a keyword and what is a library routine, for example some languages provide keywords for
input/output operations whereas in others these are library routines.
A
keyword is a featured word of a technical article. Some publications specify a fixed set of keywords from which those for a particular article should be chosen.
Keywords are a feature of the
ISP America Online; which allow one to bypass
URLs.
