Greetings,
I think I have a solution. I did some research on the Pentaho report
generator that is used in the LO Base Report Generator with emphasis on
their formula syntax. The following formula placed in the report field's
properties "Data" tab in "Data field..." seems to do what I need:
IF(LEN([Suffix])>0;"-"&[Suffix] ;"")
This tests the length of the text string (Suffix) and if not 0 then
outputs the string prefixed with a dash. The ampersand (&) concatenates
text strings. If the string length is zero, it outputs the NULL string.
I tried outputting the string here without the dash to be sure I got all
data, as in:,
IF(LEN([Suffix])>0;"-"&[Suffix] ;[Suffix])
but it fails for some reason, outputting "false" when the string length
is 0 instead.
As I said, it seems to be working, unless I breathe on it!
Thanks for all the suggestions.

Greetings,
I am using LibreOffice 5.3.4.2 on Slackware Linux 14.2 (K4.4.75).
I have a database with a text field which may or may not be null. What
I want to do is to prefix a dash "-" before the text if the text field
is not null. At first, I tried this format:
;;;"-"@
Somewhere, not by me, it got changed to:
[>0]"";[<0]"";"";"-"@
However, this does not work. I get the text when not null, but not the
dash in either case.
Is there another way to do this?
Thanks.
