" Range errors"

When this option is enabled, your program will check for range errors. Some possible causes of range errors are:

• Attempts to assign or read in values which are not assignment compatible with a particular type to a variable of that type. For example given the declaration below:

   var bit : 0..1;

  the assignment below will cause a range error:

   bit := 2;

• Attempts to access element outside of array bounds. For example given the declaration below:

   var x : array[-4..10] of integer;

  the attempt below to reference an out-of bounds array element will cause a range error:

   x[-5]
