One of the more troublesome aspects of using a cross-platform file adapter is dealing with the end-of-line problem. On UNIX, a single \n represents an end-of-line. The file front end translates either a single \n or the \r\n sequence to an ASL end-of-line marker (eol), which eliminates this problem.
Consider a file with one line, “hello world":
h e l l o w o r l d \r \n
Whereas, on a UNIX system, this file contains the characters:
h e l l o w o r l d \n
Using the file front end on either system feeds the following input stream into the rule set:
h e l l o w o r l d eol
