Close
 
Stream I/O function to terminate access to a device

Syntax

result = Close [[#]filenum ] [, [#]filenum ...]
or
Close [[#]filenum ] [, [#]filenum ...]

Parameters

filenum
List of file numbers to close.

Description

Closes the files whose file numbers are passed as arguments. If an unused file number is passed, Close returns an error.

Close without arguments closes all the files presently opened.

Terminating the program using an End statement will automatically close all files.

Return Value

Close returns zero (0) on success and a non-zero error code otherwise.

Example

' Create a string and fill it.
Dim buffer As String, f As Integer

buffer = "Hello World within a file."

' Find the first free file number.
f = FreeFile

' Open the file "file.ext" for binary usage, using the number "f".
Open "file.ext" For Binary As #f

  ' Place our string inside the file, using number "f".
  Put #f, , buffer

' Close the file.  We could also do 'Close #f', but it's only necessary if more than one number is open.
Close

' End the program. (Check the file "file.ext" upon running to see the output.)
End
