E2190 Thread local variables cannot be ABSOLUTE (Object Pascal)
A thread local variable cannot refer to another variable, nor can it reference an absolute memory address.
program Produce; threadvar secretNum : integer absolute $151; begin end.
The absolute directive is not allowed in a threadvar declaration section.
program Solve; threadvar secretNum : integer; var sNum : integer absolute $151; begin end.
There are two easy ways to solve a problem of this nature. The first is to remove the absolute directive from the threadvar section. The second would be to move the absolute variable to a normal var declaration section.
