Arrange Formulas
After the formulas have
been created, they must
be arranged in the
optimum sequence by
selecting formulas and
using the “Move Formula”
icons. This sequence is
usually according to their
qualifier - from least likely
to occur to most likely to
occur.
In the example pictured above, a series of formulas are
designed to output all the data in a bar code that follows a series
of “0”s. For instance, if the actual bar code data is “000045678”,
the desired output would be “45678” (the original minus all the
0s at the beginning of the string). If there are six 0s (Formula 1 -
pictured above), then Formula 1 specifies the output begins at
the seventh position. If there are five 0s, then Formula 2 dictates
that output begins at the sixth position, etc. If, instead, we were
to place the qualifier for two 0s above (before) the qualifier for
six 0s, then Formula 2 stipulating two 0s would activate even if
there were six 0s because the qualifier would stop looking for 0s
after it had found two. In this case, all qualifiers with three or
more 0s would be disregarded, which would not be a desirable
result.
The “Everything Else” Formula
If a formula is entered into the Data Editing Area, then all
scanned bar codes will be evaluated according to this formula. If
the scanned bar code does not satisfy the requirements of the
Qualifier(s) (see page 57), then no data is output. Practically
speaking, the scanner has been set up to scan only bar codes
that are defined by the Qualifier(s). No other types of bar codes
can be scanned.
The answer to this problem is to end the sequence of formulas
with a formula that has no Qualifier and whose modifier includes
all the scanned data (starts at position 1 and outputs “all
remaining”). An example of this can be seen as Formula 7,
pictured above.
