Compound assignment operators
Post by Alincon on Nov 6th, 2016, 11:22pm

"Compound assignment operators (+=. ‑=, *=, /=) are provided. "

I would like to see some examples of using Compound assignment operators: what does += do?

Thanks
r.m.

Well, instead of Code:
counter = counter+1
you write Code:
counter +=1
.
And instantly make your code uncompatible with majority of BASIC's.
(You may not care actually - one always code "here" and "now")

Visual BASIC has them, BBC BASIC has them, PowerBASIC has them.... (and of course they're ubiquitous in most other programming languages like C++, Java, Python etc.).

Also bear in mind that the compound assignment operators aren't just faster to write, they execute more quickly too.
