expandlf - expand an RMSfile
expandlf datafile #records
This command expands an existing hashed RMSfile so that it contains
the
number of records specified by the #records argument. If #records
has
a leading plus (+) sign, the RMSfile is expanded by that many additional
records. If #records has a leading minus (-) sign, the RMSfile is
contracted by that many records. If there is no leading sign, the
RMSfile
size is changed so that it contains the number of records specified
by
the #records argument. This command expands the named RMSfile in
place.
If there is insufficient disk space to hold both the original file
and its
expanded copy simultaneously, the RMSfile cannot be expanded.
If the datafile argument has the form dbname ~lfile or ~lfile, expandlf
expands the RMSfile using the database name dbname and the logical
file
name lfile. If the datafile argument has the form filename (i.e.
it has
neither a ~ nor / in the name), then it is taken as a logical file
name,
filename, using the default database name.
