I thought that I would give a sort of review and step through manual for DISK FILE MANAGER which is an Oliger utility. So far as I know there is not a manual for this software that is in public domain. The program is all in BASIC and occupies 10,022 bytes so for those that want to improve or change it and are programmers it is easy to do.
DISK FILE MANAGER LOADs with a report of “0 OK, 601:1” and either RUN or GOTO 1 will initialize it. First screen prompt, “Source Drive?”
Enter that and get prompt, “Destination Drive?”
Enter that and get prompt, “Is Above Correct?”
Enter “Y” for yes and get the menu. NOTE: if you have the T/S 2040 printer plugged in and turned on when you do “LOAD DRIVE ? CAT” (? stands for the drive you selected for the Source drive) the printer will PRINT out the CAT of the source drive. This is what the menu looks like:
Disk File Manager LOAD DRIVE 0 CAT INDEX AND SAVE MOVE FILES LPRINT DRIVE 0 CAT FORMAT ANY DRIVE RENAME FILES RESTART ME QUIT ME
To select the options use the space bar to move the cursor downward only. If you over shoot then it will jump to the top when it reaches the bottom. To select a cursor marked selection hit the ENTER key.
MOVE FILES is a copy option. It will copy the disk in Source Drive to the destination drive. The drives do not have to be the same (40 track to 80 track or the reverse but of course the copy terminates with disk full prompt). To copy LOAD source drive’s CAT, in other words hit ENTER with the cursor on LOAD DRIVE ? CAT and it will LOAD the CAT and step through the files and then ask SORT? (sort into alphabetical order) N will get you back to the MENU or Y will sort the files and then it will get back to the MENU. Move the cursor down to the MOVE FILES option and hit ENTER. You will get a prompt “Have You LOADed the CAT?” If N for no will return you to the MENU. If Yes hit Y and ENTER and then the CAT will be displayed on the screen with the cursor on the first entry. If you want to MOVE that file hit the ENTER key if you want to skip moving it hit the SPACE BAR. If you want to MOVE (copy) all files just hold down the ENTER key and it will step through and will also start the copy procedure. When all entries are marked or skipped then the prompt: “Place New Disk in Drive ?” and a flashing prompt: “Hit ENTER TO MOVE Files “?”. When that is done the drives get busy MOVEing the files from source drive to destination drive. Finishes with prompt: “Hit ENTER for MENU”
In addition to MENU you get a report of how many cyls FREE in each drive.
INDEX AND SAVE: CAT must be LOADed. It SAVEs as disk name and type as “disk name C ARR” but I don’t know what to do with it. I could not LOAD it again. (Anybody know?”
LPRINT DRIVE? CAT: if CAT not LOADed gives ERROR: “2 variable not found, 580:1” This outputs to a large printer, I needed to add a line advance since it all printed on one line.
FORMAT ANY DRIVE: CAT does not need to be LOADed. First prompt: “Which DRIVE? (0-3” When drive entered get second prompt: “TRACKS/INCH: 40/80” I entered 42. Third prompt: “Is the above correct?” If N is entered goes back to ask “which drive?” If Y get fourth prompt: “Name for Disk?” You are allowed 16 characters (I know that you LarKen users are crowing since with the LarKen you can almost write a book but on the other hand the Oliger allows any ten characters for a file name instead of six a period and mandatory type plus one more character) and after name is entered and you hit ENTER the FORMATting starts with the following prompts: below prompt for name is displayed the disk name you entered and at bottom is displayed “FORMATting” and again gives disk name. I modified my working copy of DFM ABC so that it stops when FORMATting is complete. Otherwise it flashes very fast the directory of the disk and back to the DFM ABC menu. In line 960 there was a PAUSE that I changed to STOP that I wanted for personal reasons. To return to menu on my version I hit CONT. and ENTER.
RENAME FILES: CAT must be LOADed. Selected file(s) will be prompted: “RENAME File Name to?” and then after that is entered get prompt: “Correct?” If correct the disk drive will operate and other file names will be presented till all are processed. When all files are done prompt: “Hit ENTER for MENU” appears.
RESTART: Goes back to start of DFM ABC in other words to enter source drive and destination drive.
QUIT ME: gets: “9 STOP statement, 150:2.
I had DFM ABC for quite a while before I started to use it and now I use it to FORMAT all my Oliger disks. The main reason for that is the Oliger EPROM that I have is version 2.64 and the default is to 80 tracks. This way I don’t have to remember to change the track from 80 to 40 (LET /T=42) each time I use it.
