+.TH total "" "" "/rdb Command"
+.PC "Sum a column"
+\fBtotal [ \-l ] [ \fBcolumn ...\fB ]  < \fItable\fR
+.PP
+.II "column^add"
+.II table^add
+The command
+.B total
+adds up the values in each
+.I column
+in
+.IR table .
+If no
+.I column
+is named on the command line,
+it totals every column in
+.IR table .
+.PP
+The option
+.B \-l
+prints the entire table as well as the total for each
+.IR column .
+.PP
+Several other commands behave just like
+.BR total ,
+except that the value they produce is not a total but:
+.BR datatype ,
+.BR maximum ,
+.BR minimum ,
+.BR mean ,
+.BR precision ,
+.BR width ,
+.BR length ,
+and so on.
+The all call the same program, but decide
+what to print depending upon the name used to call it.
+.SH Example
+There are two formats.
+Without the option
+.BR \-l ,
+.B total
+just gives the head lines and the total line.
+For example, to find the totals of columns
+.B Debit
+and
+.B Credit
+in table
+.BR journal ,
+type:
+.DM
+	total Debit Credit < journal
+.DE
+.PP
+This returns something like:
+.DM
+Date    Account Debit   Credit  Description
+----    ------- -----   ------  -----------
+                65000   65000   
+.DE
+.PP
+However, if you wish to see the whole table, as in a report, type:
+.DM
+	total -l Debit Credit < ledger
+.DE
+.PP
+This returns something like:
+.DM
+Account Date    Debit   Credit
+------- ------- ------- -------

+101     890103          5000
