The "pause" part of system("pause") is Windows-specific.

You could use the Run function from the exec package to the same effect.

If all you want to do is pause until the user presses enter, add 'os'
and 'bufio' to your import list and try:

bufio.NewReader(os.Stdin).ReadBytes('\n')

  bufio.NewReader(os.Stdin).ReadBytes('\n')

*Thanks*

Do you mean pause in cmd.exe ?
That should call with following.

"cmd /c pause"

Thanks.

too long to write this every time:
8g hello.go
8l -o hello.exe hello.8
created for this program .bat file to compile and run alone.
You only have to enter the file name.
This is the code - .bat file:

@echo off
color 2
title Go compiler
echo Go compiler
set /p name=Enter file name:
:start
cls
echo Go: %name%.go
start 8g %name%.go
start 8l -o %name%.exe %name%.8
IF NOT EXIST "%name%.8" DEL %name%.exe
IF NOT EXIST "%name%.8" msg * Compiled problem
IF EXIST "%name%.8" start %name%.exe

Note that this is only good once.
If stdin is not a user typing at a terminal
it may buffer more bytes past the \n it
is looking for. And then because the
reader is discarded after this line, the
bytes are gone.

Perhaps it should be:

func Pause() os.Error {

buf := make([]byte, 1)

for {

c, e := os.Stdin.Read(buf)

if c != 1 {

return e

}

if buf[0] == '\n' {

break

}

}

return nil
