DAVID'S DUAL DISK DRIVE AID The program is designed to run on a Commodore 64 with a dual disk drive (either the 4040 or the MSD-2). It's primary purpose is to transfer selected files from drive 0 to drive 1. When the program is run, the following menu of 20 choices is presented. BOTH DRIVES : A LOAD DIRS INTO MEMORY ----------- B SEE DIRS IN MEMORY COPY 0 TO 1 : C SELECTED FILES ----------- D ALL FILES (- FORMAT) E ALL FILES (+ FORMAT) DRIVE 0: F LOAD DIR INTO MEMORY ------- G SEE DIRECTORY H DELETE FILES I RENAME FILES J VALIDATE DISK K INITIALIZE DRIVE DRIVE 1: L LOAD DIR INTO MEMORY ------- M SEE DIRECTORY N DELETE FILES O RENAME FILES P VALIDATE DISK Q INITIALIZE DRIVE R FORMAT DISK DRIVE: S RESET THE DRIVE ----- T STATUS Any of these options can be selected in two different ways - by pressing the appropriate letter (e.g. N if you wanted to delete a file in drive 1), or by using the cursor up and down keys, and then pressing the RETURN key. The first thing you should do is to place the disk to be copied in drive 0, and the receiving disk in drive 1. Pressing A will load both directories into memory, and then display them. (Using F and L will load the directories from 0 and 1 separately. You should use these whenever you change the disk in a drive.) Any command which affects the directory, e.g copy, automatically rereads the revised directory. Pressing B allows you to see the directories of both disks after they have been read into memory. Once you have both 0 and 1 in memory, C, D, and E, will allow you to copy from 0 to 1. C permits you to select particular files for copying while displaying the remaining blocks free in drive 1. You first select all the files and then the copying is done in one go. If you choose more files than there is room for, no copying is done. D copies all files to 1 without overwriting files in 1 (i.e. it is the COPY command). E first formats 1 and then copies all files from 0 (i.e. it is the DUPLICATE command). G (and M) let you see the directory of 0 (or 1) in memory, or it can be used to view the directory on disk (without loading it into memory). H (and N) allows you to choose those files you want deleted. Like C, you first select all to be deleted before they are deleted. I (and O) permit any filename to be renamed. J (and P) validates the disk, and rereads the disk directory. K (and Q) initializes the drive. R formats the disk in drive 1. S and T allow you to reset the drive (UI), and read the error channel. There are four commands which are not displayed on the screen. The F1, F3, and F5 keys allow you to change the colors to suit your taste. F8 loads DAVID'S DIRECTORY DESIGNER (D.D.D.) if you are fortunate enough to own one!
