I was able to get the Fortran and C examples in 
SYS$COMMON:[SYSHLP.EXAMPLES.CXML] to compile and run.

I was not able to be the C++ example to compile, but I'm more interested 
in Fortran and C so it doesn't bother me.

In order to get the Fortran examples to compile, link and run:

$@SYS$COMMON:[SYSLIB]CXML$SET_LIB VAX  (IEEE is another option, but 
didn't run on my ALPHA)

$FORTRAN/INCLUDE=SYS$COMMON:[SYSLIB] file.for  (this picks up the 
missing CXMLDEF.FOR Include)

$ link file.obj  (didn't need to do anything special here, just ordinary 
link)

$ r file  ( this works )

I think I'll try installing CXML first, then Fortran and see what 
happens.  I saw someone who recommended installing CXX before CC on 
ALpha, so there may be a hidden correct order.
