1 May 91 R. H. Waterman 132 "I" Street Chula Vista CA 91910 Dick - Enclosed is the disk with MBASIC.COM. It also contains the program HELP.COM and several Help files. You might want to try HELP CPM and HELP MBASIC. They should provide some useful information to you. Again I urge you to make copies of each of these disks at your earliest opportunity, use the new ones as your working copies, and put these away in a safe place. That way, if disaster strikes, you can always recreate your working disk. The easiest way to make the copies is with the COPY command. But, first be sure that the notch on the side of the disks that I sent is covered with a piece of tape. It write protects the disk. With your machine booted up and the System Disk in Drive A enter COPY. You will be presented with a menu of several choices, the first of which is 'C COPY' followed by a paragraph of explanation. Press the 'C' key. This will present you with a new screen of instructions. Follow these, and you will soon have a working copy of your system disk. Remove this from Drive B and label it right away. Remove also the System Disk from Drive A and set it aside. You should now be back at the main menu of COPY.COM. Press the 'C' key again, and again follow the instructions - this time with one of the other disks that I sent you in Drive A and a blank disk in Drive B. Follow through with the instructions and you will have a working copy of the second disk. Repeat this process until you have made working copies of all ten disks that I sent. Put away those ones I sent in a safe place! Spend some time reading your book from Weber. I'm sure it has some good stuff in it. Have fun, and good luck! Don Maslin 7742 Via Capri La Jolla CA 92037
