A keyword is an identifier with a special meaning and function in a programming language.
Keywords include reserved words (such as begin
or
while
) and modifiers (such as reintroduce
or absolute
) (see also Free Pascal reserved words).
Lazarus will usually display keywords in Pascal text files (source code) in bold black characters using syntax highlighting. Use [IDE options|Editor|Colors] to change.
Some very common Free Pascal words like read
or write
, are in fact procedure
names, not keywords.
