Using the WITH LISTING IN Option
The WITH LISTING IN clause specifies a filename where compile time warnings are sent. After you compile a UDR, this file holds one or more warning messages. This listing file is created on the computer where the database resides.
If you do not use the WITH LISTING IN clause, the compiler does not generate a list of warnings.
On UNIX™, if you specify a filename but not a directory, this listing file is created in your home directory on the computer where the database resides. If you do not have a home directory on this computer, the file is created in the root directory (the directory named “/”).
On Windows™, if you specify a filename but not a directory, this listing file is created in your current working directory if the database is on the local computer. Otherwise, the default directory is %INFORMIXDIR%\bin.
