file_location_frequency number
In the residual listing SNAP includes information about the name of the input data file and the line number in the file from which observations have been read. This is to facilitate checking and editing the data file. To avoid cluttering the output listing this is only done after about every 20 observations. The frequency of this information can be changed with the file location frequency command. The parameter of the command is:
number
Specifies the frequency with which information about the source of data is included in the list of residuals. Use 0 to suppress file location information. If observations are sorted (with the sort_observations command) then the frequency must be 0 or 1.
