CCSD3ZF0000100000001NJPL3IF0PDS200000001 = SFDU_LABEL RECORD_TYPE = STREAM PRODUCT_CREATION_TIME = 1991-09-20 OBJECT = TEXT NOTE = "Notes on using the index table." END_OBJECT = TEXT END NOTES ON USING THE IMAGE INDEX TABLE The index table contains one row (record) for each image file on MDIM Volumes 1 through 6. Images in the POLAR subdirectories on Volumes 1 and 6 are not identified in the index. The index table is formatted so that it may be read directly into many data management systems on various host computers. All fields (columns) are separated by commas, and character fields are enclosed in quotes. Each record consists of 512 bytes, with a carriage return/line feed sequence in bytes 511 and 512. This allows the table to be treated as a fixed length record file on hosts which support this file type and as a normal text file on other hosts. The structure and content of the image index table are described in file VOLINFO.TXT located in the DOCUMENT directory. A label coded in the Object Description Language (ODL), providing a formal description of the index table structure, is located in file IMGINDEX.LBL. For personal computer users a DBASE DBF structure is also provided in the file IMGINDEX.DBF. This file should be copied to magnetic disk and can then be used to load the IMGINDEX.TAB file into DBASE III or IV with the following commands (assuming the MDIM CD-ROM is loaded in drive L:): .USE IMGINDEX .APPEND FROM L:\INDEX\IMGINDEX.TAB DELIMITED Once the table is loaded into DBASE, it can generally be automatically loaded into other data managers or spreadsheets which provide search and retrieval capabilities.
