I don't know if this will help you understand, but here's how you can
solve your problem. It's all about knowing the words at your disposal
from the library..
( scratchpad ) {
V{ { 1 "e" } { 1 "f" } { 1 "g" } }
V{ { 2 "a" } { 2 "b" } { 2 "c" } }
} flip concat .
{ { 1 "e" } { 2 "a" } { 1 "f" } { 2 "b" } { 1 "g" } { 2 "c" } }
Cheers,
Jon
