|
|
Chr$(13) + Chr$(10) |
End-of-line (carriage return, linefeed) |
||

||
|
|
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 |
