[Jprogramming] string comparison

[Brian Schott]

I think my cmp is like yours. It works by boxing the string argument
before comparing the numeric result of grade.


   cmpnum =: *@-~
   cmpalpha=: cmpnum/@\:@,&<
   cmp =: cmpnum :: cmpalpha
   'abc' cmp 'abcd'
_1
   'abc' cmp&< 'abcd'
_1
   ('abc';'f') cmp 'abcd';'f'
_1
   ('abc';'f') cmp"0 'abcd';'f'
_1 1
   3 cmp"0] 2 3 8
_1 0 1
   3 cmp"0] 2 ;'abc'
_1 _1
   3 cmp"0~] 2 ;'abc'
1 1
