Programming Style

This manual follows the guidelines below in presenting Visual Basic code:

Reserved words are in lowercase with an initial capital letter.

Dim intSomeValue As Integer, strTextValue As StringintStartNumber As Integer
' If, Then, and Str are reserved words.intSomeValue = 0 Then strTextValue = Str(intStartNumber)

Variable names begin with a lowercase prefix, followed by a lowercase word or words with an initial capital letter. Variables are declared at beginning of an example.
```
Dim dblIncome As DoublestrFirstName As String * 30
```
Line labels are used instead of line numbers for error-handling routines and for On...GoSub and On...GoTo statements.
```
On Error GoTo ErrorHandler
.
.
.:
    MsgBox Err.Description
```

An apostrophe ( ' ) introduces a comment.

' This is a comment; these two lines
' are ignored when the program is running.

Control-flow blocks and statements in Sub and Function procedures are indented.
```
Sub SomeCode ( )
    If intX > 0 Then
        intP = intQ
    End IfSub
```
