It's pretty easy:
1) it says just "copy into ijs window and execute"
2) the phrase
".(noun define)-.LF
already explicitly removes the line breaks
after reading up to leading ")".
NB. ---- copy into ijs window and execute --------------------
".(noun define)-.LF
bridge=:(<./@(>@(2&{))({...@],(1&{...@],&.><@[),(2&{...@]-.&.><@[),3&}
....@],<@[)])^:(*...@#@(>@(1&{)))@(((((>@{...@[-.]);>@{:@[)}.@(([-.[-.
])/))@(>@(0&{)(([<....@]){.])"1(,:|.)@(/:~)@(>@(1&{)))([>@{~(>@(
2&{)@]<&(<./)>@{:@[)+.#@(>@{:@[)=#@(>@(1&{))@])])({...@],(1&{...@]-
.&.><@[),(2&{...@],&.><@[),3&}...@],<@[)])^:(*...@#@(>@(1&{)))^:_&.(({

)
