Re: st: Trouble with maxcnt command as part of prvalue calculations

[Richard Williams <richardwilliams.ndu@gmail.com>]

Scott Long has just posted an update that raises the limit to 35. If 
that still isn't enough for you it is easy enough to just put the 
program into a text editor and change it to whatever you want. 
adoupdate isn't showing the update yet, at least on my machine, but 
you could probably run it tomorrow. Or you could probably do -findit 
spost9- and force it to install now.
You could also probably just run the margins command to get what you want.
