>>I am parsing Medical HL7 format records. I'm using fgets() to read them as a flat file. Some of the record formats have interpretations of the data that exceeds the 8192 maximum length of the fgets. When I get the data if the length is less than 8192 then it is obvious the length is what it is. If the length of the data is 8192 how can I tell if the fgets completed because of a CR or there is more data for that record?

This is what I tried but the fgets doesn't return the chr(13)
