Why? It currently returns a perfect make object!. Not to question your knowledge, but to enlargen mine. ;)

Yes, & no: nw-lyt: compose/deep[ wrd: [(first l)] tp: [(second l)] spc: [(third l)] (if [length? l > 3] [ vls: fourth l ]) ] returns: ** Script Error: Out of range or past end ** Where: do-boot ** Near: fourth l I guess compose doesn't execute an 'if?

because. ;) Well, it is difficult for me to explain... One reason is that I need to be able to handle ALL parameters of a layout. If you look at the object 'lyt which I have defined, make object! [ wrd -- (word) The name of the layout tp -- (type) Maybe I should use a different name, but it contains 'layout + any refinements spc -- (spec) The specs of the layout pr -- (parameters of the refinements) Currently it is not always created, but I will probably change that ] then the other reason is that the layouts get DOne when they are viewed. I need them to not be in the global namespace. Block! maybe better, I am just not sure. Thanks!! Ammon
