MS-DOS

= SYMPTOMS =

Automap Road Atlas for MS-DOS may cause the system to stop responding (hang) when your perform any calculation on computers without a math coprocessor or computers without an Intel microprocessor installed.

= RESOLUTION =

  Restart the computer.   From the MS-DOS command prompt root directory (for example C: if your hard drive is drive C), type SET NO87=XYZ and press ENTER.   Restart Automap. NOTE: SET N087=XYZ can be added to the AUTOEXEC.BAT file. Adding the entry to the AUTOEXEC.BAT file establishes the setting when the computer is turned on. 

= MORE INFORMATION =

The SET N087=XYZ environment variable setting disables the program’s ability to use a math coprocessor during calculations. The problem may occur when trying to display the Distance Line, a Table of Directions, or whenever the program attempts to use the math coprocessor.
