Checking a program that bombed, I came across this line of code.
C eval @CurrOptFntSiz *= (1+(@PzFactor*.01))
I don't think I recall seeing *= in an eval statement.
The compiler certainly accepted it.
Is this multiplying @CurrOptFntSize by (1+(@PzFactor*.01)) and setting @CurrOptFntSize equal to that?
That's exactly what it is, Charlie! That's a C-language syntax
shortcut: a *= b is short for a = a*b. It becomes important when you
have longer variable names and you cut and paste. Imagine this one:
MyLongVariable1 = MyLongVariable1 * SomeFactor;
MyLongVariable2 = MyLongVariable2 * SomeFactor;
MyLongVariable3 = MyLongVariable2 * SomeFactor;
MyLongVariable4 = MyLongVariable4 * SomeFactor;
Notice the problem? It doesn't occur here:
MyLongVariable1 *= SomeFactor;
MyLongVariable2 *= SomeFactor;
MyLongVariable3 *= SomeFactor;
MyLongVariable4 *= SomeFactor;
Just one of those little nice to have features.
