[fpc-pascal] How are Assigned, Free, Nil and Destroy related?

When the loop runs again Assigned in InitVars is false so as soon as those
FBreakStrings and SCStrings are accessed within the loop a SIGSEGV occurs.
So what I want to know is whether Assigned  remains true when Free is


See my previous answer. 
There is a helper function "procedure FreeAndNil(var obj);" that calls
obj.free and sets obj to nil. So instead of SCStrings.Free; SCStrings:=nil;
call FreeAndNil(SCStrings);
