Does anyone think that the shorthand syntax is a little backwards?
It replaces this format: X = X + 1 with X += 1. Shouldn't it be X =+ 1? It's a little easier to visualize putting the X in between the = and + than having to reverse it.


I realize that C and it's derivatives do it that way, I just think that it's a little odd. JMHO.

Hans, would it be possible to have the compiler handle both ways?

Interesting question. Apparently, the first version of C actually implemented it as "x=+1;". It was quickly changed to "x+=1;" when it was realized that the former had a another and more common interpretation.

(If it's still not obvious what the issue is, think of the difference between "x=-1;" and "x-=1;", and consider that the former was allowed in the RPG IV language long before the latter was.)

Cheers! Hans
