Hi Jesus,

Thanks for taking the time to reply. It is much appreciated.

In the context of a report, they are the same thing to me. You define a
variable via the Report GUI Designer (I still don't know how to do it
from code), that variable is then available for use anywhere in your
report. ie: gloabal ;-)

I'll take a look at that, thanks.

Huh? You lot me there. So if they are not used, why do those properties
still exist in TfrReport?

Sorry, it was a typo. I meant Report.Script.

As far as I understand, LazReport is based on some open source version
of FastReport. Due to the lack of documentation (or updated
documentation) of LazReport, I looked at the documentation for
FastReport and tried to use some if what it suggests. But it seems much
of it doesn't translate to LazReport.

Here is the URL of FastReport I looked at.

https://www.fast-report.com/documentation/ProgMan/index.html?adding_a_variable.htm

I worked through the whole "Working with a list of variables" section.
