Select Bitwise to have e-Biz Impact perform a bitwise operation
on the contents of the Qualification Object Information windows’s
FldObj or Datalink field. The actual contents of the FldObj or Datalink are
not changed. If the result of the bitwise operation is false or
zero (0), the qualification fails.

Operator
|
Select the bitwise operator from the
drop-down list to use on the contents of the Qualification Object
Information windows’s FldObj or Datalink field. Available operators
are:
On – the bit indicated by the
Bit Loc field is on. The bits of the field object or datalink are
numbered from left to right, starting with zero (0).
Off – the bit indicated by the Bit Loc
field is off. The bits are numbered from left to right, starting
with zero (0).
& – performs a bitwise AND between
the referenced field object or datalink and the value provided for
Literal Value/Datalink/Input Field.
| – performs a bitwise OR between
the referenced field object or datalink and the value provided for
Literal Value/Datalink/Input Field.
^ – performs a bitwise EXCLUSIVE
OR between the referenced field object or datalink and
value provided for Literal Value/Datalink/Input
Field.
>> – performs a right bit shift. The newly
opened places are filled with zero. Supply the number of places
to shift in the Literal Value/Datalink/Input Field fields.
<< – performs a left bit shift. The
newly opened places are filled with zero. Supply the number of places
to shift in the Literal Value/Datalink/Input Field
fields.
~ – performs a bitwise complement. For
example, if you have “0101”,
the complement is “1010”.

Bit loc
|
This field appears only when on or off
is chosen as the operator. Select the bit you want to evaluate.
If the bit selected is beyond the scope of the data, the Qualification fails.
|
Literal Value
|
This field appears only when &, |,
^, <<, and >> operators are used. Select this to use a literal
value as the second operand. Enter a value in the entry field.
|
Datalink
|
This field appears only when &, |,
^, <<, and >> operators are used. Select this to use the contents
of a datalink as the second operand. Enter the name of the datalink
object or select the Down Arrow to choose from a list of existing
datalink objects.
|
Input Field
|
This field appears only when &, |,
^, <<, and >> operators are used. Select this to use the contents
of a Field object as the second operand. Enter the name of the Field object
or select the Down Arrow to choose from a list of existing Field
objects.
