Abstract

This method allows an unlimited number of PC files to be distributed on a host computer as a single file by blocking the files together into one file. The format of the BLOCK command is: BLOCK drive:/path/search string. The search string allows for *'s and ?'s to group PC files with a given pattern, similar to the DOS 'dir' command. The output, the blocked file, is a composite of all the requested files. It is in the format: Tot.#files/filename1/#bytes1/chksum1/filename2/#bytes2/chksum2/... ...chksumN; The first record is the total number of files that are blocked into the single file. After the total number of files, the pattern repeats in the format of the individual filename, the number of bytes in the file, and a check sum that is calculated to verify data integrity.
