OK. No quotes.

My UDFs are in c:\XXXXX, and I specify :

UdfAccess = Restrict UDF;"C\XXXXX"

The first bit works: an unqualified path is treated as relative to the
root directory. the correct entry to access UDFs in both rd\UDF and
c:\XXXXX is:

UDFAccess = Restrict UDF;c:\XXXXX

>Also, what is UdfAccess Full ? Surely one must define a path?

You must define a fully qualified path *in the declaration to the
database*. For example, if you set UDFAccess = FULL then your database
declarations for udf libraries located in c:\XXXXX would be like this:

DECLARE EXTERNAL FUNCTION abs
DOUBLE PRECISION
RETURNS DOUBLE PRECISION BY VALUE
ENTRY_POINT 'IB_UDF_abs' MODULE_NAME 'c:\XXXXX\ib_udf.dll';
