Declaring columns
Rpv Reports accepts to declare
some values in the configuration section to use them as columns.
This is useful for changing all the values modifying only
one value in configuration section.
To declare a column, will be required that the column has a name
that begins with "$" char. After that,
you can type the name you want for the column containing even
spaces.
Example:
$COL_0=400
The value will be expressed in twips and after this declaration
"{400}" will be the equal {$col_0} (lower or upper case doesn't affect
the final result).
Additionally, in HEADER and DATA sections, is possible to specify the columns
using the following syntax:
{$COL_0 + 100} This text will be printed in the
position $COL_0 plus 100 twips
It is possible also to use columns in all those
commands that require X coordinates.
If you have declared columns, simply click on
the "columns" button of the toolbar to see them. Additionally, they can be moved
with the mouse.

| It is desirable
(but not required) not to declare columns with long names
because it can affect the performance of the viewer and
server; specially the viewer (let's remember that even
when the system is slow, it will be faster than most of
printers). |
