Field1 = 'BRYCE';
if Field1 = 'BRYCE';
is much nicer (I think) than
Field1 = 'BRYCE';
if (Field1 == 'BRYCE');
I *constantly* get tripped up in JavaScript (I don't code much C) using
'='
when I should be using '=='...
Agreed. But there's a reason for the syntax, and that is that assignment
can be done anywhere - even in an equality test.
For example (in C) if (a = 3) will always be true and a will always equal 3
at that point, because what's really being said is:
a = 3
if (a)
Hence the need for different operators. This feature is highly exploited in
statements like:
if ((fp=fopen(szFilename, "r")) == NULL) { // handle error...
The above assigns the result of fopen to fp... and then tests fp against a
value of NULL.
The equivalent doesn't exist in RPG, which is precisely the reason RPG
doesn't have/need an assignment symbol that's different from the equality
test symbol. And the reason those other languages do.
