Batch commands and their parameter names are not case sensitive (thus LOG, Log, log, and LoG are all equally valid). Parameter values which are not matrix specific are not case sensitive (“Save = yes” or “save = YES” or “Save = Yes” are equally valid). However, the values of parameters which refer to specific matrix names, row, or column names are case sensitive. Thus saving an output matrix under the name of “Output” will be different than saving it under “output”, and trying to use “data = datamatrix” is different than “data = DataMatrix”. Case-sensitivity of file names depends on the operating system (e.g., file names are not case sensitive under Windows, but they are case sensitive under Linux and Mac OS X).
