  How can I get mathematica to read in a text data file without 
first having to massage the data in a text editor?  Take your 
typical multi-column data from an excel-type spreadsheet.  If I 
save it as text, the ReadList function assumes I want to 
multiply all numbers together than appear on the same line.  If 
I save it as comma delimited, ReadList says it is a syntax 
error.  I have tried manipulating the RecordSeparator and 
WordSeparator options in  ReadList, but no success.
  My current wordaround is to take the data file, read it into 
excel and save it as comma delimited text, then import it into 
word, and do a global replace on all return characters 
converting them into commas, placing a { } around the list, 
saving it as unformatted text.  Then ReadList can read the data 
and I can Partition it.  I hope there is a more elegant 
solution.
  P.S. Has anybody been able to figure out how to read in 
bitmap data like in the cat picture in the 3.0 "tour of 
mathematica"?  Any time I try to read in .bmp files, it just 
generates garbage.  Not quite as "mathematica reads in data in 
any format" advertised.
