Rationale

The language design attempts to be as small and simple as possible while still being sufficiently expressive to be able to specify reasonably conceivable rules.

These design choices have been made to keep it simple to implement, read and learn with easily predictable behaviour:

• No heap memory allocation (stack variables only)

• No global variables

• End of line separates statements (expressions can be split over lines)

• No general purpose user defined functions

• Only integer arithmetic (64 bit precision)

  Note that integer arithmetic means that a/b where a is less than b will evaluate to zero. This means that a percentage calculation needs to be expressed as (100*a)/b rather that (a/b)*100. Further, if higher precision is required in percentages then a “percentage times constant” scheme should be used. For example you can use a “per mille” system using a constant of 1000 where 70.3% would be specified as the integer 703.
