Ouch, Ouch. It hurts when you shoot yourself in the foot. I could not figure out
why this would not work, until I compared some of the v/test files with those I
had generated from Appgen. I had been incorrectly entering my working directory
into the HOMEV field instead of "v's home". Big difference!

This already sets up a pointer to _myCmdWin in the modeless dialog constructor.
The Canvas object is declared in cmdw.h, but is private. Lazy, lazy Phil moved
it to public. I can send text to the TextCanvas by:

_myCmdWin->ETCanvas->DrawText("alsdj;\n");

How bad is having the canvas public?
