Hi, Mikael,
A simple refinement to append is all that is needed:
c: [["a" "b"] ["c" "d"]]
d: make block! []
foreach cc c [
append/only d cc
]
probe d
By the way, it is not necessary to reassign the result to your word, 'd.
Append appends the result to the block (or series) and returns that head as
a convenience. Using probe d will confirm that you have your result.
Hope that helps.
