H2: Description

The {{character}} variables are the preferred way of
including the respective symbols. A format-specific configuration file
can override the default definitions of these symbols.

The {{environment}} variables can be used to find out which version
of SDF is executing and where it is installed.

The {{expression format}} variables define bits of Perl code to
format variables or expressions. They can be defined in a
configuration file - your system adminstrator may wish to
configure date formatting to suit local conventions.
