Hello all,

Have run into a situation where I have a UDF which needs more than 10 input 
parameters, but when I try to declare it in DDL the engine reports the 
following error:

This operation is not defined for system tables.
SQL error code = -607.
Invalid command.
External functions cannot have more than 10 parameters.

With my 18+ years of using IB/FB I never ran into this issue, never had to use 
a UDF with more than 5 params, so I was surprised by the error.

Is there a 'real' reason why there is a parameter limit?  Or, is it a case that 
a limit was required for syntax purposes and someone thought that 10 was a good 
number?


Sean
