The command
|
|
.B update
|
|
uses
|
|
.B blank
|
|
when it updates a record.
|
|
.B update
|
|
temporarily replaces the record it is updating with a blank record.
|
|
This blank record serves as a record lock; this ensures
|
|
that other users cannot read
|
|
or update the record while it is being updated, but it leaves the
|
|
rest of the table available for use.
|
|
.PP
|
|
Please note that when you pull up a blank record,
|
|
it means that that record is being updated by someone else.
|
|
Come back to it later.

Note the spaces between the tab (^I) and the dollar sign `$'
|
|
that indicates the end of the line.
|

The spaces replaced the
|
|
characters, including spaces, that were in the original records.

|
|
Note too that the column names are untouched, so that this
|
|
is a perfectly correct file as far as the
|
|
.B /rdb
|
|
commands are concerned, it just contains no data.
