Worse... I work around this... whatever it is.. by changing the definition:
$ ijconsole
appendbox=:1 : 0
y
:
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'
)
1 'a' appendbox 2
|value error: y
| y
9!:14''
j701/2011-01-10/11:25
How can I be getting a value error on y? Why is the monadic definition
being used in the dyadic case? How can I get anything done when things are
this crazy?
Can anyone else reproduce this?
Thanks,
