Re: EXPORTing procedures

[Mark Waterbury <mark.s.waterbury@xxxxxxxxxxxxx>]

Hi, Scott,

IIRC, some of this behavior was changed recently, e.g. with recent TR levels, for at least 7.3 and 7.4 ... so, your idea of "missing PTFs" may be "spot on"?  :-)

Brian,

Your code works for me.   I copy/pasted it, did not add "export", and it 
worked without any troubles.

Perhaps you are missing a PTF?
