On VMS you can copy files with the /CONTIGUOUS switch to specify that
the output file must occupy contiguous physical disk blocks. Of course
the default is /NOCONTIGUOUS.
I vaguely remember using the /CONTIGUOUS switch to copy MDM (MicroVAX
Diagnostic Monitor) diagnostic files from one bootable MDM disk to
another. I forget if that is necessary for proper operation of MDM.
