Writing Records into a File in Sequential Order SPL uses the FWRITE intrinsic to write all or part of a record in a sequential file with fixed- or variable-length records. A logical record pointer points to the next record to be written. When any part of a record is written, the pointer advances to the next record. The HP C/XL functions provide many choices for output. You may use fputs, fwrite, or write to emulate the SPL record structure. Or you may use the printf and fprintf to write formatted, variable-length text records. With the latter two, you must identify the end of each record to HP C/XL by writing a '\n' (linefeed) character. The '\n' is not actually stored in the file.
