comparison isn't defined for characters.
Single characters can be compared thus:
cle =: (-:/:~)@:, NB. eg character-less-than-or-equal
NB. other comparisons are available!
'a' cle 'v'
1
'm' cle"0 'amv'
0 1 1
But this is chat, so you probably knew that!
Cheers,
Mike

Hi all,
testing character data for equality works fine but testing for relative
order does not.
'a'<'v'
|domain error
| 'a' <'v'
'a'='v'
0
Is this explained somewhere ?
Thanks,
Jimmy
