On the page that describes the "hidecolumn" function
http://mydbr.com/doc/content/cmd.styles.html#dbr.hidecolumn
the example says "hidecolumns".
select 'dbr.hidecolumns', ColumnReference / nbr of columns from right to hide
select 'dbr.hidecolumns', ColumnReference [, ColumnReference...]
The second example should be "dbr.hidecolumn" without an "s".
select 'dbr.hidecolumns', ColumnReference / nbr of columns from right to hide
select 'dbr.hidecolumn', ColumnReference [, ColumnReference...]
Also, does "dbr.hidecolumns" allow a ColumnReference? Which reference would you use if you wanted to hide the last two columns?
