Scripting Conditional Statements with Logical Expression

[sephult]

Hi All!

I was wondering if anyone else found issues when trying logical expressions like "and" , "or" ?

Example:
if (value > 12)and(value < 24) = true then begin


I can't seem to figure out why I keep running into problems and it will not enter my condition.
Any guesses?

Well I guess I solved my issue:

FYI

if (value > 12)and(value < 24) = true then begin

should be

if (value > 12)and(value < 24) then begin

because the boolean is assumed and doesn't need to be defined for the condition.

That's correct. You also want to enclose the entire conditional part of the statement in parentheses:

if ((value > 12)and(value < 24)) then begin

I've learned that this gives more consistent results.

Thanks ahonoe,

I kept running into this on many times and couldnt figure out why...lol
Glad finally figured out, makes life easier when scripting.

True & False do not work as expected... Comparing them to conditions compiles clean, but always returns false.

Oddly, comparing them to 1 and 0 seems to work.
Just not conditions.

I agree shawnb, that's where I was getting confused. I am so used to doing the comparison and defining the result, I didn't expect that a boolean wouldn't need an expected result defined.
