Thanks, Dave.

So, is running @TT is like saying to the compiler:
 run the input from this logical 'TT' (my terminal) and direct
 its sys$output to this file.

The ctrl+z then serves as the EOL flag for the logical content?

Is it somewhat similar to when you put a $ sign to finish a 
'type sys$input' string? 

That means this is used interactively only? So to use inside a procedure,
the better way would be the other solution indicated, to create a file
and put the commands inside it, then calling @com /out=file.
Still a pretty nice solution.
