V. GENERAL INSTRUCTIONS


 CITMIX is very easy to use. You only have to provide
information on seven screens. Four of these screens contain
menus that list the acceptable choices. The other three screens
require that you input a number. In the DOS version, this number
can be either a real number or an integer because the program
will convert it to the required format. If you do not input a
valid number, the program "beeps" and redisplays the screen. The
P/OS version REQUIRES that you input a REAL number. An improper
number, such as ".r4", causes the program to either "bomb" or
calculate incorrect spray instructions.

 Once you have chosen all the necessary variables, the
program displays them for your review. At this point, you can
change any of the variables by simply pressing the letter
preceding that variable. The program redisplays the screen
listing the variable and you then input a new value. The program
again displays all the variables for your review. If the
variables are correct, you press <RETURN> to receive spray
instructions.

 On several screens CITMIX asks you to type a letter or word
as a response. This letter or word may be in either upper or
lower case letters.
