I paste a definition into my J session:
appendbox=:1 :0
:
pfx=. ,1 4{.y
assert. pfx-:,_1 4{.y
if. ' ' e. pfx do. '' return. end.
prefix=. (2{.pfx),'/',pfx
dir=: 'Reference/',prefix
(;x,&.>LF) fileappend dir,'/data06.txt'
)
And then I inspect the name
appendbox
1 : 0
pfx=. ,1 4{.y
assert. pfx-:,_1 4{.y
if. ' ' e. pfx do. '' return. end.
prefix=. (2{.pfx),'/',pfx
dir=: 'Reference/',prefix
(;x,&.>LF) fileappend dir,'/data06.txt'
)
Somehow my adverb has mutated.
What is going on here?
Thanks,
