In Lazarus, you can choose the mode ("Object Pascal - default
(ObjFpc)") and $H+ ("Use AnsiStrings") in the Project -> Options ->
Compilation Options. This is equivalent to starting all your code with
"{$mode objfpc}{$H+}".

In fact, these are already the default: ObjFpc and $H+. So, if you're
using Lazarus for your development, these are already set at nice
default values.

It seems not possible to set the "{$writeableconst off}" (equivalent
to "{$J-}") using Lazarus options. Probably because it seems not
possible to do it using FPC command-line, so Lazarus would not have
how to communicate it to FPC. Seems like a simple omission, and a
bugreport to FPC would fix it:)
