" you use your Apple I!@ computer to communicate with other Apples or with timesharing systems, then you need Data capture 4.0. If you want to save stock quotes, airline schedules, electronic mail, or other data from a remote computer system for future use, then you need a smart terminal program for your Apple II~. Data Capture 4.0 is the most user friendly and most flexible program of this type. It is specifically designed to take advantage of all the features of the Micromodem II~, but it works equally well with the Apple Communications Card@ and several other popular serial interface cards. Data Capture 4.0 is the only Apple II~ smart terminal program available which is fully copyable and modifiable. This means that you don't have to worry about backup. Go ahead and make all the backup copies you need. The unprotected format and helpful documentation make modifications to Data Capture 4.0 very easy to perform. In addition, full technical support is available by phone from Southeastern Software. Data Capture 4.0 has many other features. Incoming data files are automatically captured regardless of length. Data in the memory buffer can be viewed, edited, printed, saved to or loaded from disk, or transmitted to the remote system at any time. An unattended mode of operation is provided so that you can call your Apple from another location and send data to it or load data from it. Data Capture 4.0 is fully compatible with the Apple III~ in emulation mode. It is also compatible with all popular lower case adapters for the Apple II@, including the widely used shift key modification. An automatic logon utility for use with the SOURCE is provided with Data Capture 4.0. Also included is a HELP text file containing the latest tips and suggestions on using Data Capture 4.0 effectively (many of these are the result of feedback from customers). See your local Apple dealer today for a demonstration of Data Capture 4.0 or order direct from Southeastern Software at the address below. (Please include $2.50 for postage and handling.) If you presently own a previous version of Data Capture you may upgrade to the new version for the difference in price plus $2.50 for postage and handling.

On the back of the covering are connectors for B/W video, color video, an RGB signal and a cassette recorder. The joystick connector is on the motherboard. Presently, the BASIS comes with out BASIC ROMS and software, except for a ZAP diskette to convert Applesoft, Pascal 1.1, CPM and the Apple system monitor to 80 column format.

V4 -12v 0.5A To the right of the cursor control keys is a numeric keypad consisting of 18 keys. The keys represent the digits 0-9, the "=" , the decimal point and the operators + ,-,* and /. There is also a key marked CE which simulates the cancel line command (control X). It is worth noting that the I return key on the numeric keypad doesn't behave like a return key, but generates a Ctrl D instead. This may accomodate Pascal users, but for BASIC users it is rather inconvenient. On top of the keyboard are 15 function keys. These keys generate letters and symbols (like the type writer keys), but by referring to a special location (see below) one can determine whether a function key has been pressed. With each function key, four different values can be gener ated by pressing a function key alone or with the shift and/or Ctrl key. The layout of the typewriter keys (there are 56 of them) differ on several points from the Apple layout. For instance, the pound symbol is not located on top above the 3, but near the return key. Furthermore, on the machine I had, the Y and Z key were exchanged, which seems to be a com mon practice in Germany. However, BASIS Inc. has announced that key boards adapted to different countries will soon be available. The U.S. ver sion was scheduled for release at the end of May. 24 Call -A.P.P.LE.

Magazine • August 1982 SPELLING What The "dictionary disk" is designed to be copied and the documentation would you give tells how to do it. The main program disk is copy protected. The user is to have able to choose the speed that the pro gram will print the words by using the game paddle. I have not used this TURTLEGRAPHICS, at all, as the program seems to run at about the speed that is comfortable with for me. For others though, this may or may not be important. If any key is pressed during the listing of words, automatic scaling, the program will halt until another key is pressed, so the user does not and really need the paddles to slow down the program. The first thing the program asks four graphic is "proof read a document ?" The default answer is yes, and when modes, answered, you are instructed to remove the program disk from drive one, insert the disk with the file you including wished checked into drive 1, and the dictionary disk into drive 2, assuming HIRES and LORES, you have a two drive system. If not, the program will prompt you where and when to insert each disk. Then, on your after hitting the return key, the catalog of your data disk is shown Apple II? and you make your selection of which file to check. All that is needed is the first few letters of the file's name, and the program will load that file! This saves lots of typing, and reduces the risk of typing a file name incor rectly. Next, the program will "read" the file that you selected, and present you with several options, listing all the words in your file, listing of only the misspelled words; a list of the misspelled is one that contains the words that the program does not recognize, even though they may be spelled quite correctly. The user is also given the option of verifying each word prior to its being marked, or the marking of each word judged to be misspelled by the program. This can make the checking of a document very, very rapid. As the program "reads" your file, the screen shows the number of words in the file, and the number of words on the "dictionary disk." This is sort of interesting to watch, and with this program, you can also print out all the words you used in your docu ment, and their relative frequency of usage. The misspelled words are marked by replacing the last letter by any character chosen by the user. Call -A.P.P.L.E.

A few preceding and following words are also printed to give you the context in IBM PC, which the word in question was used. Other options include adding the TRS 80 Model II, word to the dictionary disk, ignoring the word, or deleting the word from the dictionary.

The same process may be used to delete Apple II? words from the new dictionary. After the disk in drive 1 is finished, you will have two dictionary disks. In this way you can create as many disks with specialized words as desired. By writing a list of words you wish to add to the dictionary disk, using your word processor program, you can create multiple special purpose dic tionary disks, being careful to spell each word correctly. The Sensible Speller has an op tion that almost replaces a real dic tionary. The user can ask for a list of all the words contained on the "dic tionary disk." This enables the user to ask for all words that begin with one letter or a sequence of letters. Thus, if you do not know the exact spelling of a word, but do know the first few letters, you can find the cor rect spelling if that word is in the dic tionary disk. This saves looking up the word in a real dictionary. The Sensible speller works with Apple Writer I and II and most popular word processors, as well as in emulation mode on the Apple III and separate versions are available that support Super Text, Pascal, Word Star and other CP/M pro cessors that do not compress text.
