Example productionset

For the purposes of testing, the MultExpression is in a separate productionset.

The full grammar follows:

Arithemetic Expressions
[2] Expression:=ArithExpression | MultExpression
Second RHS for testing. /* This isn’t grammatical! */
[3] ArithExpression:=Expression '+' MultExpression | Expression '-' MultExpression
[1] MultExpression:=MultExpression '*' MultExpression
| MultExpression '/' MultExpression
| Number div0
[4] Number:=[0-9]+
Division by Zero

Division by zero is an error.
