Loading using free format

When loading according to free format, the input line is divided according to separating characters (spaces, tabulators, etc.). The data in input lines, therefore, does not have to be in fixed positions.

In the imported file can be an arbitrary number of separating characters, regardless of the number of separating characters written in the format prescription (for example, if in the format prescription are the separating characters ", X="), an arbitrary number of spaces (even just one) can be in the data file.
