The FOCUS reporting language is a powerful tool for analyzing
and formatting information. The language is non-procedural-that
is, you only need to think about what information you want to present
in your report. For the most part, you can describe the report in
any order; the sequence of commands is not important.
The simplest form of report that you can produce is a tabular
report, a report whose information is arranged vertically in columns.
This is the basic report format, incorporating the fundamental reporting
concepts and command syntax. Most of the other report formats build
on these concepts and syntax.
