Const crlf = Chr$(13) + Chr$(10)
Some common uses of this function are:
|
|
|
Chr$(9)
|
Tab
|
|
|
Chr$(13) + Chr$(10)
|
End-of-line (carriage return, linefeed)
|
|
|
Chr$(26)
|
End-of-file
|
|
|
Chr$(0)
|
Null
|
|
Example
|
Sub Main()
'Concatenates carriage return (13) and line feed (10) to
'CRLF$, then displays a multiple-line message using CRLF$
'to separate lines.
crlf$ = Chr$(13) + Chr$(10)
MsgBox "First line." & crlf$ & "Second line."
'Fills an array with the ASCII characters for ABC and
'displays their corresponding characters.
Dim a%(2)
For i = 0 To 2
a%(i) = (65 + i)
Next i
MsgBox "The first three elements of the array are: " _
& Chr$(a%(0)) & Chr$(a%(1)) & Chr$(a%(2))
End Sub
