If you are already comfortable with Crystal syntax, you can continue to use
it, and benefit from the new functions, operators and control structures
inspired by Visual Basic.
Note:
• Record selection and group selection formulas cannot be written in Basic
syntax.
• Report processing is not slowed down by using Basic syntax. Reports
using Basic syntax formulas can run on any machine that Crystal Reports
runs on.
• Using Basic syntax formulas does not require distributing any additional
files with your reports.

• To learn about Basic syntax, see Creating Formulas with Basic syntax in
the online help.

in the online help.
User Function Libraries in formulas
Crystal Reports lets developers create User Function Libraries (UFLs) that
are recognized by the Formula Editor. A UFL is a library of functions that is
created by a developer to address a specific need. UFLs can be programmed
in a COM or a Java environment.
Crystal Reports lets you see COM UFLs or Java UFLs in the Formula Editor,
but not both at the same time. (You can also choose to see no UFLs.)
Note:
Java UFLs are not supported in the Report Application Server (RAS) and
the Crystal Page Server, so if a report has a formula in it, and that formula
uses a Java UFL, the report may not run in BusinessObjects Enterprise
because the formula will fail to compile.
For details about developing Java UFLs and configuring Crystal Reports to
use a UFL, see the Java Reporting Component Developer's Guide.
