- \section{Rlisp '88}
- Rlisp '88 is a superset of the Rlisp that has been traditionally used for
- the support of REDUCE. It is fully documented in the book
- Marti, J.B., ``{RLISP} '88: An Evolutionary Approach to Program Design
- and Reuse'', World Scientific, Singapore (1993).
- Rlisp '88 adds to the traditional Rlisp the following facilities:
- \begin{enumerate}
- \item more general versions of the looping constructs {\tt for},
- {\tt repeat} and {\tt while};
- \item support for a backquote construct;
- \item support for active comments;
- \item support for vectors of the form name[index];
- \item support for simple structures;
- \item support for records.
- \end{enumerate}
- In addition, ``--'' is a letter in Rlisp '88. In other words, {\tt A-B} is an
- identifier, not the difference of the identifiers {\tt A} and {\tt B}. If
- the latter construct is required, it is necessary to put spaces around the
- - character. For compatibility between the two versions of Rlisp, we
- recommend this convention be used in all symbolic mode programs.
- To use Rlisp '88, type {\tt on rlisp88;}\ttindex{RLISP88}. This switches to
- symbolic mode with the Rlisp '88 syntax and extensions. While in this
- environment, it is impossible to switch to algebraic mode, or prefix
- expressions by ``algebraic''. However, symbolic mode programs written in
- Rlisp '88 may be run in algebraic mode provided the rlisp88 package has been
- loaded. We also expect that many of the extensions defined in Rlisp '88
- will migrate to the basic Rlisp over time. To return to traditional Rlisp
- or to switch to algebraic mode, say ``off rlisp88''.
