Hi all! I spend several hours with a simple issue I don't understand. I would like to create a daily task on WinXP; I have already shortened my complex package to a very simple one, but it still doesn't work: This code works fine in the regular front end: In[1]:= ps=$PathnameSeparator; data=Import[FileNameJoin[{"C:",ps,"Temp",ps,"data.TSV"}]]; Length[data] Export[FileNameJoin[{"C:",ps,"Temp",ps,"output.txt"}],data] Pause[2]; Quit[]; Out[3]= 1996 Out[4]= "C:\\Temp\\output.txt" It also works fine using math.exe or mathkernel.exe by typing in everything manually. I have created a package c:\temp\test.m containing the code above. I can start math.exe and load the package and output.txt is created. The same happens with mathkernel.exe: Mathematica 7.0 for Microsoft Windows (32-bit) Copyright 1988-2009 Wolfram Research, Inc. In[1]:= Get["c:\\temp\\test.m"] However, if I try "C:\Program Files\Wolfram Research\Mathematica\7.0\math.exe" -initfile c:\temp\test.m or "C:\Program Files\Wolfram Research\Mathematica\7.0\mathkernel.exe" - initfile c:\temp\test.m (which are my batch commands for the daily task) , I get an error message: Mathematica 7.0 for Microsoft Windows (32-bit) Copyright 1988-2009 Wolfram Research, Inc. Import::infer: Cannot infer format of file data.TSV. Output.txt now contains Null. I also tried to give explicit importing information ("Table", "TSV", "FieldSeparator", encoding information etc.), but it doesn't work. I don't understand this. Do I need to load other .m-files (e.g. some init.m) too? The rest of my complex package (including SQL communication, statistical calculations, graphics generation) works fine, but I cannot load a simple tsv-file. My system: $Version = "7.0 for Microsoft Windows (32-bit) (February 18, 2009)" $OperatingSystem = "Windows" Are there any good references for notebook automation and evaluation using scheduled tasks under Windows? Thanks for any help!
