Modifier Key Programming Example
Selling soft drinks in different sizes is an excellent modifier application. For example, a
restaurant sells Coke, Sprite and Root Beer in 3-sizes: small, medium & large.
If the PLU number assignment is:
PLU
#
1
=
Coke
PLU
#
2
=
Sprite
PLU
#
3
=
Root Beer
You may choose to modify the 4
th
digit of the PLU number with the digit 1 for small, 2 for
medium and 3 for large. (Always count right-to-left to determine the PLU digit#.)
When the 4
th
digit is modified to a value of 1, and the Small modifier key is pressed before
the Root Beer key, the registration of PLU #1003 results.
