There ain't such thing in the context of inverted table. I wasn't asking
theoretical question. A practical scenario is importing data from excel having 2
columns for code and descriptions such as,
code descr
A aaa
B bbbbbb
C cccccccccc
They are read into rank-2 box text array and then converted into inverted table
for processing. The description cell may be very long and it may need to limit
to a certain length, so that {. is needed, say
descr=. 10{. 1{:: ivt
Someone may not fill anything in an entire text column inside excel. I think
that Henry's suggestion works for me.
< 6{.(!.' ')("1) 1{:: ifa 3 2$ 'ab';''
