INTRODUCTION 2. FILE FORMATS All document files and tables are stored as ASCII stream-record files. In a stream-record file, records (lines of text) are separated by a carriage-return and line-feed character sequence. The / sequence marks the end-of-record and the start of a new record. This organization works well for the Microsoft-DOS systems because the / sequence is identically used on these systems. On Macintosh systems, an end-of-record mark is simply a character. Macintosh text editors can read and access these files, but a special-character indicator (usually a "square box" character) will mark the "extraneous" character at the beginning of each line. On UNIX systems, an end-of-record mark is simply a character. UNIX text editors can read and access these files, but a special-character (usually a ^M sequence) indicator will mark the "extraneous" character at the end of each line. File names with extension "TAB", "LBL", "LAB", "TXT", and "CAT" are formatted as ASCII stream-record files. Tabular files are formatted so that they may be read directly into many database management systems of various computers. All fields are separated by commas, and character fields are enclosed in double quotation marks ("). Character fields are left justified, and numeric fields are right justified. The "start byte" and "bytes" values listed in the labels that describe the tabular files do not include the commas between fields or the quotation marks surrounding character fields. The records are of fixed length, and the last two bytes of each record contain the ASCII / characters. This scheme allows a table to be treated as a fixed- length record file on computers that support this file type and as a normal text file on other computers. 3.
