String Functions

[Snorre]

Hello,

First: many thanks to the HP team for the update (I love it beeing finally able to enter commented or even incomplete CAS programs).

I know, the Prime is not intended for string processing.
But it would be really nice if the string functions LEFT, MID and RIGHT would be fixed eventually (it doesn't seem like a big deal).
I'd prefer LEFT("hello",0) or RIGHT("hello",0) or MID("hello",6,1) to return an empty string. Especially MID("hello",3,-1) should behave more friendly.

Greetings.
