I tried this on Win7_64:
load'plot'
x=: i.5
y=: *: x
plot x;yand got this message in the jconsole window: (jconsole.exe:3352): Pango-WARNING **: couldn't load font ""helvetica" Not-Rotat ed 9", falling back to "Sans Not-Rotated 9", expect ugly output. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
