     CATALOG:  Reports                  AREA    :  Drawing Lines       
     Lines are often used in a report to emphasize a section of text and set 
     it apart from the rest of the report. It's easy to draw lines in R:BASE 
     reports using the Draw option on the menu. The lines are placed in the 
     report definition as text; they are not part of the field location. This 
     works fine for fields that are located for a specific size. But when you 
     locate a TEXT or NOTE field using just the W marking to indicate wrap for 
     as many lines as there is data, the lines are only printed for the first 
     and last lines of data. R:BASE only wraps the data, it does not wrap 
     other text on the line.
     To have the report "draw lines" around all of a variable length TEXT or 
     NOTE field use a TEXT variable instead of the line draw character on 
     each end of the field location.  The variable contains one line draw 
     character for each line of data that wraps. The variable is itself 
     wrapped and thus prints alongside the data. 
     Step 1
     Create a lookup table to hold the line draw characters. The lookup 
     table has two columns, an INTEGER column for the number of lines and 
     a TEXT column to hold that number of line draw characters. For example:
       CREATE TABLE Borders (numline INTEGER, border TEXT 20)
     The TEXT column length must match the maximum number of lines printed 
     for the field to be wrapped. The table defined above draws lines around 
     fields wrapped up to 20 lines long.
     Step 2
     Next, determine the ASCII code of the line draw character. If the 
     lines are single line borders, use ASCII code 179, for double line 
     borders, use ASCII code 186. 
     Step 3
     Load the Borders table with data. Enter consecutive numbers (to number 
     each row) in the numline column. Enter that many line draw characters 
     in the border column. Make sure you enter enough rows. For a single-line 
     border around a field that will be a maximum of 10 lines long, load the 
     Borders table with this data:
       numline          border
       -------          -------
         1              |
         2              ||
         3              |||
         4              ||||
         5              |||||
         6              ||||||
         7              |||||||
         8              ||||||||
         9              |||||||||
        10              ||||||||||
     The data can be loaded by selecting the Borders table from the Info 
     menu. To enter the single line character, hold down the [Alt] key and 
     press 179 on the number pad. The Copy data option can be used to make 
     data entry quicker. Alternatively, the LOAD command can be used from 
     the R> prompt.
     Step 4
     Modify the report. Define two new variables in the report, one to 
     compute how many lines the field wraps on, and one to lookup the 
     matching number of line draw characters. For example,
       vnumline INTEGER = ((SLEN(note_column)) / 40 + 1)
       vborder = border IN borders WHERE numline = .vnumline
     The variable vnumline equals the number of lines required to print 
     the note_column column for a given row. It is calculated as follows: 
     SLEN finds the number of characters of data in the column for that 
     particular row, that value is divided by the located width (40) and 
     one is added to account for the last line. The variable vborder 
     contains the same number of line draw characters as there are lines 
     to print. 
     Locate vborder at both ends of the location for the note_column 
     column. You can locate vborder on top of the existing line draw 
     characters. Locate vborder only one character wide by pressing S 
     to mark the beginning, backspace, press W (on top of the S) to wrap, 
     and then press [ESC] twice. This wraps the border lines as the text 
     is being wrapped. The report format might look like this:
                     two locations for vborder 
                  /                              \
                /                                 \
               |                                   |
       D       +-----------------------------------+
       D       WS                                 WW
       D       +--------------|--------------------+
                      location of the wrapping column 
     If you have data that still doesn't print a complete box for some 
     rows of data try SET WRAP OFF. With WRAP ON, fields may wrap with 
     extra spaces causing the line count to be wrong.
