Description

D4 maps the last 16 hexadecimal digits in GUID next to the 8 digits in D1, plus 4 digits in D2, plus 4 digits in D3 as described in TGUID.

GUID specifies a globally unique identifier, represented by a string literal enclosed by brackets. The GUID declaration must have the form:

['{GUID}']

or

['{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}']

where each x is a hexadecimal digit (0 through 9 or A through F).

D4 maps the last 16 (4 plus 12) hexadecimal digits next to the 8 digits in D1, plus 4 digits in D2, plus 4 digits in D3 in this GUID string literal:

['{D1-D2-D3-D4(first_4_digits)-D4(last_12_digits)}']
