Description:
The expression input routine is a LISP function, Mathread [ ] with associated definitions, which reads in expressions such as (A+3-F(X,Y,Z)). Its result is an equivalent S-expression. The syntax of allowable expressions is given, but (unlike ALGOL's) it does not define the precedence of the operators; nor does the program carry out any explicit syntax analysis. Instead the program parses the expression according to a set of numerical precedence values, and reports if it finds any symbol out of context.
