Thanks for the information: indeed the three lines above allow a CLD code in a TEX file to be typeset by ConTeXt, using the TeXShop engine created with your indications.
By the way, as you guessed the third line can be either
]]--
or
]]


> @Hans, the problem with TeXShop is that it seems to refuse to process files whose names do not end in .tex, AFAIK.  (The typeset button is disabled.)  So a straightforward solution seems impossible.  You can always type "context file.cld" in a terminal window.
