Hi,

I have fixed the interpreter so that read watch are automatically 
disabled on end of file only for pipes, process and standard input streams.

You must run your weird code step by step to understand what happens.

Moreover, 'Read #hWatchFile, tmp' is a Gambas 2 syntax. You must not use 
it in your test project. Beware that it does not read the contents of a 
string, but a Gambas string binary format, and it fails. See the 
documentation.
