Assigning string to different string types and how the runtime environment behaves regarding them. Memory allocation, reference counting, indexed access to chars and compiler errors described briefly where applicable. var SS5: string[5]; {a shortstring of 5 chars + 1 length byte, no trailing `0`...
Counting references on strings is thread-safe. Locks and exception handlers are used to safeguard the process. Consider the following code, with comments indicating where the compiler inserts code at compile time to manage reference counts: procedure PassWithNoModifier(S: string); // prologue: Inc...
