+    This function is defined in rtl\alpha\debugstb.s.  There, it calls

+    do a call_pal callkd, which in the NT PALcode will invoke the

+
+    The normal firmware PALcode has no AlphaKd support, so DebugPrint is

+    The DestinationString is initialized to point to the SourceString

+
+    This is a copy of the same function in \nt\private\ntos\rtl\string.c.
+    It is here to minimize what the linker drags into the image.

+Arguments:
+
+    DestinationString - Pointer to the counted string to initialize
+
+    SourceString - Optional pointer to a null terminated string that
