Entering RDFSCAN Commands
HP NonStop RDF System Management Manual—524388-003

DISPLAY
DISPLAY
The DISPLAY command enables or disables the display of line (record) numbers in
subsequent RDFSCAN output.
ON
enables the display of record numbers.
OFF
disables the display of record numbers.
Usage Guidelines
The DISPLAY function is automatically enabled if pattern matching is enabled and is
automatically disabled if pattern matching is disabled.
For information about enabling and disabling pattern matching, see the MATCH
command description later in this section.
Examples
Suppose that $SYSTEM.SANFRAN.RDFLOG is a file generated by RDFFLTO, that
the RDFSCAN pointer is positioned at record 2947, and that pattern matching is
disabled (no match pattern has yet been defined in a MATCH command). To display
the next four records in the file with the record numbers showing, enter the DISPLAY
ON command followed by the LIST 4 command:
Enter the next RDFscan function you want: DISPLAY ON
File: $SYSTEM.SANFRAN.RDFLOG, current record: 2947, last
record: 2955
Enter the next RDFscan function you want: LIST 4
Record number: 2947

2004/06/11 16:10:01 \LAB1 $RDFCOM 835 STOP UPDATE

record: 2955
Enter the next RDFscan function you want:
