This might be totally irrelevant, but, if (a) the data to be read by the program during a given run is known when the program is run/launched, (b) that data is purely textual and (c) that data can be read by the program from the stdin channel, then my idea is (1) before the launch, put that data into a file named, say, inputfile.dat, and then (2) launch the program with a command like
call program.bat <inputfile.dat Moreover, if the program needs to output textual data, and can do so using stdout, then the data can be sent to another file named, say, outputfile.dat as follows: call program.bat <inputfile.dat >outputfile.dat Finally, if the program can read its data from a given file and possibly needs to output its data, again, to a named file, and those files' names can be read from the parameters to the call, then call program.bat inputfile.dat outputfile.dat can be used.
