Argument
item
Specifies the type of information to be returned. Specify one of
the following keywords (do not abbreviate these keywords):
Data
Item Type Information Returned
CAPTIVE String TRUE if you are logged in to a captive
account. The system manager can define
captive accounts in the user authorization
file (UAF) by using the Authorize utility
(AUTHORIZE).
CONTROL String Control characters currently enabled
with SET CONTROL. Multiple characters
are separated by commas; if no control
characters are enabled, the null string
("") is returned.
DEFAULT String Current default device and directory name.
The returned string is the same as SHOW
DEFAULT output.
DEPTH Integer Current command procedure depth. The
command procedure depth is 0 when you
log in interactively and when you submit
a batch job. The command procedure depth
is 1 when you execute a command procedure
interactively or from within a batch job.
A nested command procedure has a depth of
1 greater than the depth of the command
procedure from which the nested procedure
is executed.
DISIMAGE String TRUE if you are logged in to an account
that does not allow you to directly invoke
images (for example, RUN is not allowed).
The system manager can add or remove the
DISIMAGE attribute for accounts in the UAF
by using AUTHORIZE.
INTERACTIVE String TRUE if the process is executing
interactively.
KEY_STATE String Current locked keypad state. See the
description of the DEFINE/KEY command
for more information on keypad states.
MAX_DEPTH Integer Maximum allowable command procedure depth.
MESSAGE String Current setting of SET MESSAGE qualifiers.
Each qualifier in the string is prefaced
by a slash (/); therefore, the output from
F$ENVIRONMENT("MESSAGE") can be appended
to the SET MESSAGE command to form a valid
DCL command line.
NOCONTROL String Control characters currently disabled with
SET NOCONTROL. Multiple characters are
separated by commas (,); if no control
characters are disabled, the null string
is returned.
ON_CONTROL_Y String If issued from a command procedure,
returns TRUE if ON_CONTROL_Y is set. ON_
CONTROL_Y always returns FALSE at DCL
command level.
ON_SEVERITY String If issued from a command procedure,
returns the severity level at which the
action specified with the ON command is
performed. ON_SEVERITY returns NONE when
SET NOON is in effect or at DCL command
level.
OUTPUT_RATE String Delta time string containing the default
output rate, which indicates how often
data is written to the batch job log
file while the batch job is executing.
OUTPUT_RATE returns a null string if used
interactively.
PROCEDURE String File specification of the current command
procedure. If used interactively, the
terminal device name is returned.
PROMPT String Current DCL prompt.
PROMPT_ String TRUE if a carriage return and line feed
CONTROL precede the prompt.
PROTECTION String Current default file protection.
The string can be used with the SET
PROTECTION/DEFAULT command to form a valid
DCL command line.
RESTRICTED String TRUE if you are logged in to a restricted
account. The system manager can define
restricted accounts in the UAF by using
AUTHORIZE.
SYMBOL_SCOPE String [NO]LOCAL, [NO]GLOBAL to indicate the
current symbol scoping state.
VERB_SCOPE String [NO]LOCAL, [NO]GLOBAL to indicate the
current symbol scoping state for verbs.
(For more information, see the description
of the SET SYMBOL command.)
VERIFY_IMAGE String TRUE if image verification (SET
VERIFY=IMAGE) is in effect. If image
verification is in effect, then the
command procedure echoes input data read
by images.
VERIFY_ String Returns the prefix control string set by
PREFIX means of the SET PREFIX command.
VERIFY_ String TRUE if procedure verification
PROCEDURE SET VERIFY=PROCEDURE is in effect. If
command verification is in effect, then
the command procedure echoes DCL command
lines.
