A disadvantage of Pascal, the lack of preinitialized data, can be
diminished by making use of the possibilities of the EM optimizer.
For instance, initializing an array of reserved words is sometimes
optimized into 3 EM instructions. To maximize this effect you must initialize
variables as much as possible in order of declaration and array entries
