Hi, Mat,
You're almost there! Here's a complete example (using a string for
the original raw data)...
rawdata: {
Saloon:Red
Coupe:Red
Coupe:Yellow
Pickup Truck:Red
Pickup Truck:Yellow
Pickup Truck:Orange
Pickup Truck:Blue
}
finaldata: []
foreach line parse/all rawdata "^/" [
if parse/all line [
copy type to ":" skip copy color to end
][
either colors: select finaldata type [
if none? find colors color [
append colors color
]
][
append finaldata reduce [
type reduce [color]
]
]
]
]
foreach [type colorlist] finaldata [
print [type ":" tab colorlist]
]

... or, more simply...
foreach carline read/lines %file [
;...
]
since you can use the block of lines directly in FOREACH.

You don't. Blocks are mutable values, so when you APPEND to a block
you are modifying its content -- even if it happens to live inside
another block.
Hope this helps!
