Table 5-5 Command Acceptance of Naming Conventions - MOUNT Command
In MPE V/E, the name V.G.A indicates that V is the name of a volume set, that G is the
name of a group, and that A is the name of an account.
MPE/iX accepts that name in that form, but no interpretation is made as to the referencing
of G and A. Instead, MPE/iX treats V.G.A as a single, long string name, just as it would
treat A_VERY_LONG_NAME-FOR_SOMETHING.
As a convenience to established Hewlett-Packard users, MPE/iX accepts the naming
convention that was used for MPE V/E private volumes. Thus MOUNT V.G.A succeeds and
MOUNT V accesses the same volume set, provided you are logged on to account A, group G.
The MPE V/E commands are able to default the logon account and group.
However, VSRESERVE V succeeds only if there is a volume set V in existence. The MPE/iX
commands do not call up any default specifications for group and account. VSRESERVE
V.G.A succeeds only if a volumeset V.G.A is online. With all MPE/iX VSxxxxxx
commands, the .G.A component of this name is interpreted as a string, neither more nor
less specific than _G_A.
If a volume set is named according to the MPE V/E naming convention (V.G.A), you must
use an unambiguous reference when using the MPE/iX volume set commands.
Various user commands that give you access to your logon group's home volume set
implicitly initiate reservation requests if the volume set is not reserved already. An
example of one of these commands (BUILD) is:
BUILD VFILE;DISC=500,10,1;REC=-80;DEV=VCLASS1
To issue a reserve request programmatically, you may issue an FOPEN call referencing a
file residing on an unreserved volume set; this causes an implicit user initiated reserve
request. An FOPEN reserve remains in effect until a corresponding FCLOSE intrinsic call is
issued. The programmatic request is used when a single job/session step requires a certain
volume set. Refer to the MPE/iX Intrinsics Reference Manual (32650-90028) for a
description of a programmatic reserve request.
