WORKSHEET FILE FORMAT FROM LOTUS INTRODUCTION AND QUICK REFERENCE Copyright(c) 1984, Lotus Development Corporation 161 First Street Cambridge, Massachusetts 02142 (617) 492-7171 Electronic Edition, December, 1984 All Rights Reserved PREFACE Lotus Development Corporation's 1-2-3(TM) and Symphony(TM) perform user selected operations upon a data matrix that is termed a "worksheet". Worksheet files are such matrices stored on disk. A worksheet file is an unbroken sequence of binary coded records defining a single worksheet. Both 1-2-3 and Symphony accept externally created data files if the files are in the worksheet file format. Other programs can decode and process worksheet files created by 1-2-3 or Symphony. The following document provides information required to create or access a worksheet file by describing the records used to create a worksheet file. It is assumed that the reader is familiar with Lotus products and has ready access to 1-2-3 or Symphony documentation. Note that the worksheet files for 1-2-3 and Symphony are similar, but not necessarily interchangeable. 1-2-3 and Symphony share some record types, but also have record types unique to that product. Symphony can read 1-2-3 records, but 1-2-3 cannot read Symphony records. The information contained in this document has been released into the public domain and is not considered to be confidential or proprietary although still the copyright and property of Lotus Development Corporation. All efforts have been made to ensure that this information is clear and useful since Lotus will not be providing customer assistance with this booklet. Lotus will, however, incorporate any necessary corrections if they are reported in writing to: Lotus Development Corporation Worksheet File Format 161 First Street Cambridge, MA 02142 WORKSHEET FILE FORMAT Worksheet files are organized as an unbroken sequence of variable length binary records. Each record consists of a 4-byte header followed by the record body. The header defines the record's type and length, as the example below shows. The header's composition is as follows: Byte Number Byte Description 0,1 Record type code 2,3 Record body length (bytes) Example: Record Header Record Header Record Record Type Length Byte Number 0 1 2 3 Hex Code 1C 00 20 00 Decimal Equivalent 28 32 The record body can be of many different types; most have predetermined length, but some vary in length. The record type code is 28. In a hex dump of the file, the record type appears as 1C 00h, noting that the 8086/88 stores the most significant byte of word in the higher memory address. The record length is 32 bytes. In a hex dump of the file, the record length appears as 20 00h. Record types with Column/Row Coordinates Some record types contain column/row coordinates to identify a cell, or one of the two points that define a range. Numbering starts at zero in the upper left corner of the worksheet. For example: Cell A1 = column 0, row 0 SUMMARY OF RECORD TYPES This section describes the different record types found in 1-2-3 and Symphony. There are to Quick Reference tables ordered by Opcode and by Product, followed by a detailed reference section ordered by Opcode. In the reference section, there are examples for the more commonly used records. It is assumed that the reader is familiar with 1-2-3 or Symphony and has access to Lotus' documentation.
