Re: Demo file problems: script versus command line

Show all headers | View raw

Dear Ethan,
Many thanks for the most helpful response. Your suggestion was 'spot on' and I now have simple.dem operating correctly. Now all I need to do is to find out what's up with airfoil.dem ("airfoil.dem", line 132: ';' expected)...

Again, thank you!
Adrian Land
