1.Delphi Language

Inline Variable Declaration

The Delphi language in 10.3 has a fairly core change in the way it allows far more flexibility in the declaration of local variables. Until now, following classic Pascal language rules, all variable and constant declarations had to be done in a var or const block written before the beginning of a function, procedure or method code.

The new inline variable declaration syntax allows you to declare the variable or constant directly in the code and assign a value to it directly in the same statement. It is also possible to declare variables in a nested code block, with visibility and lifetime limited to that nested block.

Type inference

Variables declared inline also benefit from type inference. You do not need to specify a type for an inline variable with a direct assignment, as it can get inferred from the value assigned to it.

Traditional Memory Reference Counting in the Linux compiler

The Linux 64-bit compiler in 10.3 has been ‘reverted’ to using the non-ARC implementation of object memory management, matching exactly the Windows behavior.

The NEXTGEN define has been disabled for the Linux 64-bit compiler.

AnsiString / AnsiChar on Linux

RAD Studio 10.3 Rio has enabled support for the older-style AnsiChar/AnsiString data types on Linux. Use them with care, given Unicode is the preferred string type also on Linux and that Ansi code pages on Windows and Linux won’t match. However, this can help increase compatibility with existing low-level string management code.
