Yes thanks I understand.
My Foo function used out of bounds fill elements internally to be able to
manipulate rectangular arrays of generated indices which are of course ⎕IO
dependant.
The return result of Foo had removed them. I will not do so and my problem will
disappear.
thanks again and r
Hi Peter,
no there isn't. Fill items and Fill functions occur all over the place
in APL2.
And they are function specific so that ↑ has other fill items (' ' and
0) than
+ (0) and × (1). On the other hand fill items are not at all related ⎕IO.
You can easily achieve what you are after like thi
Is there a nice way to set the fill element for arrays?
Right now it's 0 for numeric and ' ' for character.
Because my function, that is deliberately ⎕IO agnostic, produces an m by n
array of different length vectors as a result of using X←(⊂matrix)foo¨matrix.
These vectors are certain indices i
