Create a new UUID and return it as a binary string.
Syntax:
_UuidCreate() -> cBinUuid
Note:
Xbase++ SL1 was introduced the function UuidCreate() in xpprt1.dll, so to avoid conflics the ot4xb function UuidCreate() was renamed to _UuidCreate() in build 1.5.2.2
Also to preserve compatibility with previous ot4xb versions when not using SL1
was added the following directrive to ot4xb.ch
#pragma Map( UUIDCREATE, "_UUIDCREATE" )
