It depends upon which EBCDIC variant the platform was running but IIRC with Western European platforms it would be a speech mark. But I take your point.

But since the sequence is a b c d e f g h i etc. why not apply magic to the -- operation and use the numbers as Base 26.

So a decrement would of ab would become:


'ab' = (1*(25*1))+(2*(25*0)) 

'ab'-- = (1*(25*1))+((2*(25*0))-(1*(25*0))) 
       = (1*(25*1))+((1*(25*0))
       = 'aa'

Then 'a'-- would always = -1 and decrements become OK with a predictable behaviour.
