Hi, since your question has nothing to do with Ada and all with VMS vs
Unix, I guess you'll be luckier asking it on comp.os.vms

Good luck, Gautier

I did not receive the original question, but presuming all of it is
included above:

	If you are looking for a scratch directory on VMS from
	an interactive or batch process, use SYS$SCRATCH:.  In
	the default case it equates to SYS$LOGIN:, but in some
	situations the system manager (or the user) might have
	made different arrangements.

	Note that this is the arrangement for the VMS operating
	system, having nothing particular to do with VAX.  It is
	also true when VMS runs on Alpha or Itanium.  It is not
	the case when a VAX is running any of the various *IX
	operating systems.  I don't know about when the VAX is
	running the VAXeln operating system.

	The contents of SYS$SCRATCH: is not automatically deleted
	by the operating system, some system manager who has set
	it to be separate from SYS$LOGIN: might make such an
	arrangement.

	On the VMS system where I am typing this, there is a
	separate Scratch area set up by the system manager for
	each user, and _I_ have defined my SYS$SCRATCH: to
	point there.  It must be a separate area, or else
	two users who both wanted to create FOO.DAT would
	interact with each other.

If the VAX is running Unix, it will have a /tmp directory just like
any other Unix system.

If it's running VMS / OpenVMS, then you should say so.  Preferably,
you should say so in comp.os.vms.

Incidentally, several of your questions (size, how often it's used,
whether it's purged) are going to vary from one individual system to
another, depending on the whim of the administrator, on either Unix or
VMS.
