Not yet. My best so far is to put common rules in an object like: Rules: make object! [ Label: [Alpha some Alphanumeric] ] then refer to the rule in another object like: Parser: make object! [ Label: Rules/Label Action: [ Label ( ; Do stuff here ) ] ] My next thoughts are to request object/path support in 'parse rules from Rebol HQ. Something like: Action: [ Rules/Label ( ; My action here. ) ] would be good to add to Rebol's 'parse dialect. Andrew Martin ICQ: 26227169 http://members.nbci.com/AndrewMartin/

Andrew, have you tried this: r1: [r1: [any string!]] r2: [r2: [some word!]] a-parser: make object! compose [(r1) (r2)] regards david --- Andrew Martin <[Al--Bri--xtra--co--nz]> wrote:
