>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?

You cannot tell a difference from FGETS() but you can use FSEEK(nFileHandle,0) to track a file pointer in a file. The difference between previous an current value should allow you to determine both cases.
