NEXT Command
•
The FROM command automatically displays the trace-file header record (record 0)
when it opens the new trace file.
•
The FROM command does not close a log file if one is specified.
NEXT Command
The NEXT command displays records starting from the next record in the trace file. The
number of records displayed by a single NEXT command never exceeds the number set
by the LIMIT command. Records that do not meet the current selection criteria are not
counted and are not displayed.
The command syntax is as follows:
count
specifies the number of records to be displayed. If count is omitted, one record is
displayed.
AFTER time
indicates that PTrace is to move to the first record whose timestamp is greater than
time before selecting the next records for display.
Time represents a 24-hour-clock time. You must specify the hours (hh) and minutes
(mm); you can optionally specify the seconds (ss) and hundredths (tt) of a second:
hh:mm[:ss[.tt]]
Considerations
•
Pressing the BREAK key terminates the NEXT command search or display.
•
The function keys on a Compaq 6530 terminal can be used as shorthand for various
NEXT count commands.
RECORD Command
The RECORD command displays records selected by record number. If a specified
record does not fulfill the selection criteria, it is not displayed (refer to the FILTER and
SELECT command in the PTrace Reference Manual for more information about the
RECORD command). The RECORD command never displays more than the number of
records specified by the LIMIT command.
The command syntax is as follows:
N[EXT] [ count ] [ AFTER time ]
RECORD { first [ , last ] }
{ ( first [ , last ] ) }
{ ALL }
