[javascript-dev] Re: jit.lcd - error -50 creating offscreen?

Babies.eaten = true.

Attempting to create my jit.lcd with dimensions such as
var lcd = new JitterObject("jit.lcd", 4, "char", 80,60);

returns an error:
•error: #N: bad arguments for message "jit_lcd"
•error: jsjitterobject_Constructor: null object jit_lcd
•error: js: v001.grid_selector.js: Javascript ReferenceError: jit is not defined, line 26

etc. etc.

Is jit.lcd not supported in JS? Did I miss a memo? (I missed the jit.display memo :( )
