On access to the edit formula option the flashing data entry cursor will appear after the value shown for total A/C. The
options continuation list will change and the screen will appear as shown in Figure 2-2.
The Continuation Options are:

Edit the values shown on the screen in the usual manner using techniques and
features described in Appendix A of this manual.
Values entered in the formula for aggregate feeder blends can be entered in any units desired. Blend values for each
feeder can be entered in "Tons of each component per batch", "the TPH rate of each component at plant capacity", "the
percent of each component in the total mix", or "the percent of each component in the total aggregate". In Figure 2.2 a
formula has been entered requesting 5.6X oil at 8.65 lb/gal and 2 parts of aggregate each from bins 1 and 2, no aggregate
from bin 3 and 1 part of RAP.
After the data is entered, the user keys ESCape to exit the editing process. At this point a warning label appears in the
lower right corner of the screen as shown in Figure 2.3. This warning advises the user that the computer has, if necessary,
recalculated the aggregate values so that they are specified as a percent of total aggregate, i.e. the sun of all aggregate
blends totals 100X. The formula entered in Figure 2.2 as 2 parts bin 1, 2 parts bin 2 and 1 part bin 4 now appears in
Figure 2.3 adjusted to 100%, i.e. 40x bin 1, 40% bin 2 and 20X RAP. In making this recalculation, the computer
maintained the same relative ratios between all the aggregate components entered by the user so the
formula shown should be identical to the users formula except shown on a different basis. Hit any key to see the final
WHAT YOU SEE IS WHAT YOU GET!
CAUTION --- Mix formulas can be edited while mix is being produced. If the mix number being edited is not being made at
any point in the process, then there will be no adverse or unexpected results. If, however, the mix number being edited is
currently being made, the changes entered will be effected immediately and without much opportunity for review. Changes
will not be time sequenced into place. The current target mix number can be edited, and often is, but should be done
quickly, carefully and preferably in small amounts.
