The program Evaluation provided in the ALIAS distribution is a simple example of the use of the evaluation through the parser. In its simplest form it takes as first argument a formula file and as second argument a range file (see section 12.2 for the definition of a range file) and print the interval evaluation of all the equations:
Evaluation [formula file] [range file]A third integer argument n1 may be the number of the equation we want to evaluate (the number start at 1), while if a fourth integer argument n2 is present the evaluation of the equations from n1 to n2 will be printed.
