For a learning experiment I would like to branch between scripts in the following way:

1.Run script0.exe

2. If <%block.recall.percentcorrect%> (feedback from script0.exe) is smaller than 30 % then run script1.exe,
if <%block.recall.percentcorrect%>  is between 31 % and 70 % then run script2.exe,
if <%block.recall.percentcorrect%>  is larger than 71 % then run script3.exe.

Is there a way to do this? To use a batch file won't work, will it? I guess there are opportunities to branch within scripts, but I've got ready-to-use scripts that I need for several purposes and would not like to go back and rewrite everything.

Thanks a lot
