No. There are things that are expected to be available in a modern ecosystem
or for which it would be highly desirable for them to be available.

Environments that do not support those things rapidly acquire legacy status
and then unusable in a modern environment status.

BTW, the above is not a Free Pascal comment, but more of a general observation.

As for VMS and Pascal, there is a very decent implementation of that language on
VMS, so what's the problem when a product aimed at a different environment will
not run on every environment.

So how capable are the OO features in VMS Pascal these days ?

BTW, about portability, the Free Pascal people say this on their website:

|Free Pascal is a mature, versatile, open source Pascal compiler. It
|can target many processor architectures: Intel x86 (16 and 32 bit),
|AMD64/x86-64, PowerPC, PowerPC64, SPARC, SPARC64, ARM, AArch64, MIPS,
|Motorola 68k, AVR, and the JVM. Supported operating systems include
|Windows (16/32/64 bit, CE, and native NT), Linux, Mac OS
|X/iOS/iPhoneSimulator/Darwin, FreeBSD and other BSD flavors, DOS (16
|bit, or 32 bit DPMI), OS/2, AIX, Android, Haiku, Nintendo GBA/DS/Wii,
|AmigaOS, MorphOS, AROS, Atari TOS, and various embedded platforms.
|Additionally, support for RISC-V (32/64), Xtensa, and Z80
|architectures, and for the LLVM compiler infrastructure is available
|in the development version. Additionally, the Free Pascal team
|maintains a transpiler for pascal to Javascript called pas2js.

No VMS however.
