- The CALLERS log is a random access text file with a record length of 64
- bytes.
-
- The following layout is specified in a "byte offset" format such that the first
- field begins at offset 0.
-
- Note that strings are not NULL terminated and that the length specified for
- the string is full number of useable and storeable bytes. All strings are
- padded with spaces to fill the entire field.
-
- Offset Type Length Description
- ------ ------ ------ -----------
- 0 str 62 The actual text written to the log
- 62 str 2 Carriage Return / Line Feed characters
-
- While the each record is strictly formatted to 64 bytes each making it a
- random access file - the file may be TYPE'd to the screen at a DOS prompt due
- to the inclusion of the carriage return and line feed characters at the end of
- each record.
-
- PCBoard, when displaying the callers log, takes advantage of the random access
- nature of the file format to be able to display the file in reverse order.
