Hi,

I need to activate full boolean evaluation for all my project files. I
can add  {$BOOLEVAL ON} into each single project file, but how can I
add the difective in Lazarus so it gets used for all files ?

Many thanks.

Boolean evaluation can only be changed with the compiler directive,
thus you need to use it in each file or put it into an include file
and include that in each file.

Please note that with $BOOLEVAL ON code like the following will
trigger an exception depending on the input values (in this case if
SomeObj is Nil):

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i if
Assigned(SomeObj) and SomeObj.CheckSomething then
