Subject UDF, how to declare them
Author Vander Clock Stephane
hello,

in IB_udf2 i see :

* Note: This function is NOT limited to
* receiving and returning only 255 characters,
* rather, it can use as long as 32767
* characters which is the limit on an
* INTERBASE character string.

DECLARE EXTERNAL FUNCTION ltrim
CSTRING(255) NULL
RETURNS CSTRING(255) FREE_IT
ENTRY_POINT 'IB_UDF_ltrim' MODULE_NAME 'ib_udf';

but when i try to do "select ltrim('...256chars...') from ... when i
receive an exeption numeric overflow ?

with 255 char it's ok !

did i do something wrong ?
