using macros. In macros have some of the desirable
characteristics of functions in other languages. Collections of
macros can be stored in source files.
In versions 2.7 and 2.71, the language contains 224
(previous versions had fewer) primitives,
which are the commands preceded by an asterisk in the Index (Appendix I)
to The book. From these we can build more complex operations,

Base files are precompiled internal tables that loads faster than it loads the original source files. Thus, they are closely analogous to TEX's format files.
