I'm trying to use graphviz addon by Oleg Kobchenko in J602. After Package
Manager successfully completed the installation, I run bin\install.bat and
then, in J console,
load 'graphics/graphviz'
graphview 'G{a->b',LF,'}'
The error message is:
|value error: spawn
| out=.y spawn(jpath ADDONDIR,'bin\',PROG),' ',cmdline
What could be wrong with this?
Thank you,
Alexander
