The following table gives the
.B /rdb
and \*(UX equivalents for most common dBASE commands.
The slug in \fBbold\fR characters gives the dBASE command; the following
description gives the
equivalent in

All data-base systems have some method for
importing text files.
Sometimes you'll be able to
use the header information that comes with
.B /rdb
tables,
and sometimes you'll have to specify this information
to the target system anyway.
