[mercury-users] waiting for an enter

[Tom Wouters]

i was trying to write an interactive application which requires the 
mercury program to wait for an enter on stdin a few times.

i tried

io__read_line(_R1),
...
io__read_line(_R2),
...

but the program only seems to wait for the first read_line, and skips 
the others. Even when i use actual variables, which i later print it 
still only waits for the first line...
anybody any ideas what's wrong?

thx, Tom
