The program PS1KB.EXE allows you to enter the degree symbol on a
PS/1 386 SX.  The program is a terminate and stay resident program (TSR)
which correctly handles the degree symbol.  You can enter the degree symbol
by typing Alt 248 on the numeric keypad.  The program only needs to be run
once each time you start your system.  You can run the program only when
you want to enter the degree symbol.  Or you can change your CONFIG.SYS
file to always load the program when the system starts.  To do that, add
the following line to your CONFIG.SYS file:

   INSTALL=C:\path\PS1KB.EXE

where "path" is the name of the directory where the PS1KB.EXE program is
located.
