WITH LISTING IN Clause
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.
If you do not use the WITH LISTING IN clause, the compiler does not generate a list of warnings.
On UNIX™ platforms, 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™ systems, 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.
