Ah, you are talking about a proposed change.

It's true that the script handler (0!:0 for example) strips CR
characters from definitions. But this happens before the parser starts
working.

For example, I created a script that looked like this;

data=: 0 :0
  asdf
  jkl
)

And I ensured that each line ended with a CR,LF sequence.

After executing the script, the CR characters were not present:

   a.i.data
32 32 97 115 100 102 10 32 32 106 107 108 10

Same behavior in j807 and j902.

----------------------------------

As for the state table -- the ;: dyad hasn't had any problem with
floating point state tables that I have noticed.

Have you had problems there?

Thanks,
