Opens standard input and standard error as a file.
Syntax
Usage
Open Err [for mode] as [#]filenum
or
result = Open Err( [for mode] as [#]filenum )
Parameters
mode
Ignored.
filenum
An unused file number.
Return Value
Zero is returned if Open Err completed successfully, otherwise a non-zero value is returned to indicate failure.
Description
This command opens
stdin to read from and
stderr to write to the console allowing read and write operations with normal file commands.
The normal console commands, such as
Color and
Locate, do not work in this mode, because they do not accept a file number.
The
[For Input|Output] mode is allowed for compatibility, but is ignored.
Example
Dim a As String
Open Err For Input As #1
Print #1,"Please write something and press ENTER"
Line Input #1, a
Print #1, "You wrote"; a
Close
Sleep
