Generating UUID with _GENUUID

I have read some past posts regarding this however, I can't seem to get
this to work. I have been using the _GENUUID function and the returned UUID
field displays garbage characters.
I'm on version 7.2. Am I doing something wrong or is there a better way to
generate a UUID? I need in following example format:
123e4567-e89b-12d3-a456-426614174000

See below code:
D UUID_template Ds
D UtBytPrv 10u 0 Inz( %Size( UUID_template ))
D UtBytAvl 10u 0
D 8a Inz( *Allx'00' )
D UUID 16a

D GenUuid PR ExtProc('_GENUUID')
D UUID_template * Value

GenUuid( %Addr( UUID_template ));
