F$GETSYU() is a lexical function that returns status and identification information about the local system (or about a node in the local mixed-architecture OpenVMS Cluster system, if your system is part of an OpenVMS Cluster).


F$GETSYI (item [,node-name] [,cluster-id])


In addition to the items below, you can specify any system parameter.

Item Return Type Information Returned
AI String TRUE if after-image (AI) journaling is enabled; FALSE if disabled.
ALQ Integer Allocation quantity.
BDT String Backup date/time.
BI String TRUE if before-image (BI) journaling is enabled; FALSE if disabled.
BKS Integer Bucket size.
BLS Integer Block size.
CBT String TRUE if contiguous-best-try; otherwise FALSE.
CDT String Creation date/time.
CTG String TRUE if contiguous; otherwise FALSE.
DEQ Integer Default extension quantity.
DID String Directory ID string.
DIRECTORY String Returns TRUE or FALSE. Returns TRUE if it is a directory.
DVI String Device name string.
EDT String Expiration date/time.
EOF Integer Number of blocks used.
ERASE String TRUE if a file's contents are erased before a file is deleted; otherwise FALSE.
FFB Integer First free byte.
FID String File ID string.
FILE_LENGTH_HINT String Record count and data byte count in the form (
FSZ Integer Fixed control area size.
GBC Integer Global buffer count.
GBC32 Integer Enhanced longword version of global buffer count with a per-file maximum size of about 2.1 billion for indexed files.
GBCFLAGS String Per-file management flags for sizing of global buffer cache. Returns PERCENT if global buffer count is expresses as a percent, DEFAULT if global buffer size is determined at runtime by an algorithm using two global buffer SYSGEN parameters (GB_CACHEALLMAX and GB_DEFPERCENT); or NONE if no per-file management flags are enabled for the file.
GRP Integer Owner group number.
JOURNAL_FILE String TRUE if the file is a journal; otherwise FALSE.
KNOWN String Known file; returns TRUE or FALSE to indicate whether file is installed with the Install utility (INSTALL). However, returns NOSUCHFILE if a file does not exist (for example, the file has been installed but subsequently deleted).
LOCKED String TRUE if a file is deaccessed-locked; otherwise FALSE.
LRL Integer Longest record length.
MBM Integer Owner member number.
MOVE String TRUE if movefile operations are enabled; otherwise FALSE.
MRN Integer Maximum record number.
MRS Integer Maximum record size.
NOA Integer Number of areas.
NOBACKUP String FALSE if the file is marked for backup; TRUE if the file is marked NOBACKUP.
NOK Integer Number of keys.
ORG String File organization; returns SEQ, REL, IDX.
PRESHELVED (Alpha/Integrity servers only) String TRUE if the file is preshelved; otherwise FALSE.
PRO String File protection string.
PVN Integer Prolog version number.
RAT String Record attributes; returns CR, PRN, FTN, "".
RCK String TRUE if read check; otherwise FALSE.
RDT String Revision date/time.
RFM String Record format string; returns the values VAR, FIX, VFC, UDF, STM, STMLF, STMCR.
RU String TRUE if recovery unit (RU) journaling is enabled; returns TRUE or FALSE.
RVN Integer Revision number.
SHELVABLE String TRUE if the file is shelvable; otherwise FALSE.
SHELVED String TRUE if the file is shelved; otherwise FALSE.
STORED_SEMANTICS String ASCII string that represents stored semantics.
UIC String Owner user identification code (UIC) string.
VERLIMIT Integer Version limit number. The value 32767 indicates that no version limit was set.
WCK String TRUE if write check; otherwise FALSE.


Specifies the node in your OpenVMS Cluster system for which information is to be returned. Specify the node as a character string expression. You cannot use the asterisk (*) and the percent sign (%) wildcard characters to specify the node-name argument.


Specifies the cluster node identification number for which the information is to be returned. To get information for all the nodes in a cluster, use the F$CSID lexical function to obtain each cluster system identification number, and use the cluster-id argument of F$GETSYI to gather information about each node.
