Such an extension would really be a contribution to convenience. Admittedly somewhat more laborious, the present link to Octave is quite powerful. One can easliy read and write data with the provided *.m functions.
Until this proposal is considered it can also be suggested to utillize the log.txt file which can contain even more data. For example the output of the $strobe() functions placed in a VA code is piped to this file. One can access its content by an Octave routine constructed by the User. The reader can collect the data to a *.CSV file which can be converted to a standard *.DAT file by qucsconv.exe. An additional strong link provided by the tool.
