filename

The value of filename is the name of a file. To permit use of paths, this value is a character variable with up to 256 characters. The default value of filename is ’output.csv’. If the file specified cannot be opened, then the program terminates with an error message. Note that one file should not be assigned to multiple units. Examples of filename specifications can be seen in listening.txt, where all output is placed in ’listening.csv’, and listening1.txt, where 9 separate output files are specified.
