I found that the original input data had Windows/dos line endings (CRLF - 
0d0a). My subset of the test data still had such endings, since I had simply 
grepped out those lines and redirected them to my test file. Removing the 
extraneous CR / 0d / ^M character JUST FROM THE TITLE LINE fixed the problem. 
This seems to imply that the split function is more sensitive to such line 
endings than the regular automatic record parsing?? In any case, all's well. 

Thank you for the hint!
