hmm, do you really need "IntelPentium(R)processor"? because putting "()" in rebol-pathes will not work.. building and using paths is a bit complicated. could you use a hash! instead, like proctype: make hash!["IntelPentium(R)processor" 2 "mychip" 3] something like (untested) associate: func["change or append" block key value /local here][ either here: find/skip block key 2 [here/2: value] [repend block [key value]] ] .. associate proctype "mychip" 24 to add entries and select/skip block "mychip" 2 to get it back. without [/skip .. 2] instead of finding a key 'find could find also a value, so i use /skip's for the general case. if you are sure no value is like a key, you can drop them. some ways are if you use string-keys, never store values in strings, or make them somehow different. - Volker
