58. RAINBOW 49 OS 9 Spotlight File System Repack This month I spotlight another fine product from Chris Burke File System Repack gives you eight new tools for opti mizing the performance of your OS 9 disks Repack the most important program in the package scans the file system on your OS 9 disks and rewrites any fragmented files or directories Once Repack optimizes a file the file remains optimized until you edit or modify it Repack preserves the general order of your disk files and does not change their orderin your directory Instead it sorts files in order of increasing file descriptor sector address Repack does not require any free space on your disk to operate This means you can optimize disks that are completely full It works on any OS 9 hard disk as well as all floppy disks Additionally it lets you re claim lost sectors on your disk by using several command line options In general the more inefficiently the data is stored on your disk the greater the improvement you ll notice after you run Repack The other seven utilities in Burke s File System Repack include BA which lets you set bits in the allocation bitmap for a speci fied logical sector number or range of them BD which clears the allocation bitmap for any LSN CCheck which scans your disk for defective sectors and identifies any files stored in those sectors HDB a utility that lets you back up your hard or floppy disk to

110. Digits Solution Listing 8 shows the answer to this puzzle It uses nine variables to represent each of the nine digit positions in the three by three matrix Each variable is cycled through arange of 1 through 9 A value of 0 indi cates that the end of the range has been reached The three by three matrix is processed as if it were stretched out in a straight line Digit positions are processed from left to right Processing for each digit position bumps the digit to the next one 3 to 4 for example and then checks to see that no higher digit position has already used that number If it has the next number is used When a valid digit is found processing for the next lower digit position is called which repeats a similar action The chain ends at the digit position defined by P9 If the sum of P1 P2 P3 and P4 P5 P6 then add up to P7 P8 P9 the nine digit position values are valid and printed Ifthe configuration is not valid only a bar is printed Valid digit configurations are also sent to a disk file This program takes over 20 hours to run and I pose a challenge to the reader Can you speed it up If so send me a new version and we ll publish it Reader Challenge And now for the piece de resistance of this column the reader challenge Take the Ace King Queen and Jack of Hearts Clubs Diamonds and Spades and arrange them in a four by four matrix so that no value or suit appears more than once in any row column or
