FEATURES.TXT ************************* DOS-CALC **************************** DOS-CALC is a fully functional calculator program with many useful functions not found in other calculator programs. DOS-CALC is a DOS program, but has the files necessary to set up and run in WINDOWS, as a full screen DOS window. DOS-CALC is a program, not a TSR which uses precious memory from ALL programs. If you use a hand held calculator, you'll prefer to use DOS-CALC! DOS-CALC is the perfect tool to use for calculations not requiring the power of a spreadsheet. It has all of the standard calculator functions plus many unique features, such as: a straight line linear fit, annuity loan payment and balance, trig, log, exponents, constant memory registers, a built-in screen saver, on-line help and much more. A complete disk manual is also included. DOS-CALC has an integrated unit conversion function. There are over 400 conversions already entered, but unique to DOS-CALC is the ability to add more, up to 600 more! DOS-CALC also has a unique TABLE feature. A number of example tables are also included. A table is a list of items by description and a value. DOS-CALC allows you to open a table and select the value to be returned back to the calculator. The table feature allows you to have an unlimited amount of information readily available. This is especially useful for portable computing (in the field). You can create your own tables (up 100 tables) each containing up to 1200 entries. Tables are simple ASCII (text) files which you can easily create with a text editor, spreadsheet or database program. Of course, the best feature of DOS-CALC is that it is truly a tape display calculator. It saves your work (180 lines) even after you shut your computer off. You can scroll back and review your previous calculations. The complete tape can be printed on one sheet of 8-1/2 x 11 paper or saved as a text file. DOS-CALC just got easier to use! Starting with version 3.0, Microsoft(R) mouse support has been added. Its all automatic. If you have a Microsoft or compatible mouse, DOS-CALC will automatically detect it. There's no setup required. You can easily select any of the functions by pointing and clicking. The BEST FEATURE of DOS-CALC is its shareware price. Only $12.00 (U.S.) to register your copy and receive your own personalized registration number to remove the shareware screen. Unlike most software products, DOS-CALC's registration is a LIFETIME registration. Your registration number will validate future releases of DOS-CALC. Registered users of DOS-CALC will receive written notification of new releases. You may pick up a new release from your local ASP software vendor, ASP BBS or acquire a disk directly from DOS-CALC. The latest version of DOS-CALC is always available on CompuServe by typing GO IBMSYS and is located in the DESKTOP library section. The filename is DCALCx.ZIP, where x is the current version number (example: DCALC3.ZIP). Again, your registration number will validate your new copy (no upgrade fees required)!
