Width Statement Example

The example uses the Width statement to set the output-line width for a file.  A test file is created, and the same characters are written to two different line widths.  To try this example, paste the code into the Declarations section of a form.  Then press F5 and click the form.

 

Sub Form_Click ()

   Dim I, Msg, NL, Text                  ' Declare variables.

   NL = Chr(10)                          ' Define newline.

   Open "TESTFILE" For Output As #1      ' Create sample data file.

   For I = 0 To 9                        ' Print ASCII characters

      Print #1, Chr(48 + I);             ' 0-9 to test file

   Next I                                ' all on same line.

   Print #1,                             ' Start new line.

   Width #1, 5                           ' Change line width to 5.

   For I = 0 To 9                        ' Print 0-9 again. This

      Print #1, Chr(48 + I);             ' time, five characters print

   Next I                                ' before line wraps.

   Close #1                              ' Close file.

   Msg = "The effect of the Width statement is as shown below: " & NL

   Open "TESTFILE" For Input As #1       ' Reopen the file for input.

   Do While Not Eof(1)

      Input #1, Text                     ' Get lines from file.

      Msg = Msg & NL & Text              ' Create message.

   Loop

   Close #1                              ' Close file.

   Msg = Msg & NL & NL & "Choose OK to remove the test file."

   MsgBox Msg                            ' Display effects of Width.

   Kill "TESTFILE"                       ' Remove test file from disk.
