Back to the data types.

Range of values: processor-dependent. Examples of Intel and Intel compatible processors:

32 bit processors: 0 .. 4294967295 64 bit processors: 0 .. 18446744073709551615

Memory requirements: Examples for Intel and Intel compatible processors:

32 bit processors: 4 bytes or 32 bits 64 bit processors: 8 bytes or 64 bits

A data field of the data type NativeUInt can only accept positive integer values. Assigning other values ​​leads to compiler error messages when the program is compiled and the compilation process is aborted. That is, the executable program is not created.

Definition of a data field of the type NativeUInt:

    nuint : NativeUInt;

Examples of assigning valid values:

  nuint := 0;
  nuint := 4294967295;

Examples of assigning invalid values:

  nuint := '0';
  nuint := '4294967295';

The difference between the two examples is that the upper example is the assignment of literals of the type integer, while the assignment of the lower example is literals of the type String.
