Usage

Reset

or
Reset( streamno )

Parameters

streamno

The stream number to reset, 0 for stdin or 1 for stdout.

Description

Reset, when called with no arguments, closes all disk files.

Reset, when called with the streamno argument, will reset the redirected or piped streams associated with stdin (0), or stdout (1).

Runtime errors: Reset(streamno) can set one of the following runtime errors:

(1) Illegal function call

• streamno was neither 0 nor 1

(3) File I/O error

• Resetting of stdin or stdout failed

Examples

start GeSHi

Open "test.txt" For Output As #1
Print #1, "testing 123"
Reset

end GeSHi

start GeSHi

Dim x As String

'' Read from STDIN from piped input
Open Cons For Input As #1
While EOF(1) = 0
  Input #1, x
  Print """"; x; """"
Wend
Close #1

'' Reset to read from the keyboard
Reset(0)

Print "Enter some text:"
Input x

'' Read from STDIN (now from keyboard)
Open Cons For Input As #1
While EOF(1) = 0
  Input #1, x
  Print """"; x; """"
Wend
Close #1

end GeSHi

Note: Under Windows, to specify to the program that data entry is completed (transfer EOF), you can press CTRL+Z then press ENTER.
