Re: Two '=' On A Single Line

Well - I use this nice shortcut very often:

*in50 = ( option = '5' ); // DSPATR(PR)

But as a curtesy to the next poor soul who has to maintain my code in 15-20 years from now, I always try to put parentheses around the bool expression and put a comment about the intention (in this case the DDS).

Ahh.. that makes sense. I didn't think of it as a logical expression but a
double evaluation... :)

string = 'test' + 'this' = ' ';
This compiled, but string = '0' (zero) when done.
Weird.

Not so weird at all, of you use parentheses to show the operator
precedence:

string = ( ( 'test' + 'this' ) = ' ' );

As EQUAL has a very low precedence - the PLUS is evaluated first - then
it's result compared to ' ' and results on *OFF - which is in fact a
correct char value of '0'.
