Weird!
I'm starting to put some waits meta-info-prints in my loops. This spawns
a new question:
How is this possible ?

FOR i=0,4 DO PRINT, i, ' ', /NONEWLINE
^^^^^^^^^^ this may be a problem
Result:
0 1 2 3 4

I couldn't find anything usefull in the help. If this isn't possible I
have to use the wait :/

thx,
Tom
