Word Document Properties

Consistency:
The decision is made by using the same criteria and in the
same manner every time.
Speed:
A computer can make static decisions faster than humans can.
However, the decision must be the same every time, and the decision
must have the same answer set every time.

Complexity:
Requesting that the computer make static decisions can
reduce program complexity. Fewer decisions translate into ease of use
for most people.
All forms of 
If...Then
statements can use any expression that equates to
a Boolean value, including a variable of the 
Boolean
data type. The term
expression
refers to any equation or variable that VBA can interpret as a
means of determining when it should perform the tasks within the
If...Then
structure. The expression 
2 > 1
is true, so VBA would perform
the tasks within the 
If...Then
structure. You can also use variables for an
expression such as 
A = B
. Anything that equates to a Boolean value can be
used as an expression for the 
If...Then
statement.
Using the If...Then statement
The 
If...Then
statement is the simplest form of decision-making code. This
statement tells VBA to perform a task if a condition is true. If the condition
isn’t true, VBA ignores the statements within the 
If...Then
structure.
The example in this section checks the highlighted text in a document. To
test the 
If...Then
statement in VBA, create a Word document. Type 
Hello
,
press Enter, and then type 
Goodbye
. Then double-click the word 
Hello
to
select the text. The code in Listing 5-1 shows how a simple 
If...Then
statement works. (You can find the source code for this example on the
Dummies.com site at
