Optimization switch

Is compiler switch
Code: Pascal
[Select]
[+]
[-]
{$O-}
same as
Code: Pascal
[Select]
[+]
[-]
{$OPTIMIZATION OFF}
?
Documentation here doesn't mention it:
https://www.freepascal.org/docs-html/prog/progsu58.html#x65-640001.2.58
If it is, can it take all the values described in documentation?

Yes. Even a couple more. Most should only be of interest to highly capable programmers, though: you need some knowledge how optimization theory works...

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

From
Introduction
:
For long switches, the + or - character to switch the option on or off, may be replaced by the ON or OFF keywords.
Thus {$I+} is equivalent to {$IOCHECKS ON} or {$IOCHECKS +} and {$C-} is equivalent to {$ASSERTIONS OFF} or {$ASSERTIONS -}
