The range type represents a series of integers, for example 0..3, and Min..Max.
The start of the range is the first value in the expression, for example 0, and the end of the range is the value following .. in the expression, for example 3. The range contains all the integers between, and including, the start and end values. For example, the range expression 0..3 contains the numbers 0, 1, 2, and 3.
Range expressions only support int values, and can only be used in for, sync, race, and rush expressions.
For example:
for (Index := 0..5):
Print("{Index}")
