String Functions - Snorre - 12-04-2014 12:23 AM
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.

I agree on all accounts. In general, the string operations should return a null string if the arguments do not result in a proper substring. The MID("hello",3,-1) bug is really bad, though. On my calculator, it resulted in a crash that required a reset via the pinhole in the back.
