Why does it embarrass you to separate them like the others?

Because PCM is defined as part of the MSX Turbo R standard. Only MIDI is optional !

All official Turbo R have PCM, the Aucnet is an hidden Turbo R and does not count for the standard defined by ASCII.

THe fact that these instructions begin with CALL is not relevant, as the contrary exists with Disk BASIC.

Superimosition, Digitalization, MSX-Audio, MSX-Kanji, MSX-Music, etc also.

But nothing says it's optional or not.

In fact LOAD, SAVE, etc are instructions from MSX-Basic 1.0. These are not spécifics for "Disk Basic". The Turbo R's PCM is a similar case.

There is no any official Turbo R machine without PCM.

But maybe this Japanese page is more helpful:

https://ja.wikipedia.org/wiki/MSXturboR

"音源ではMSX-MUSICが標準搭載になったほか、8ビットPCMの録音再生機能もついた。ただし、BIOSのルーチンではPCM再生時にCPUの他の処理を止めてしまうため、他のPCM/ADPCM搭載機のように音楽の同期演奏に使うのには著しく難があり、利用例は多くなかった。後年にはVDPの走査線割り込みを利用することで並列再生させたソフトもあったが、MSXは元々1ビットD/Aのサンプリング機能を持ち、またPSGを使用しての4ビットPCM再生をさせたソフトも存在した事から、それほど注目はされなかった。"

Google translation:

"MSX-MUSIC was standardized in the sound source, as well as 8-bit PCM recording and playing function."

So MSX-MUSIC and PCM are part of the MSX Turbo R standard defined by ASCII, even if the instructions begin with CALL.

Another proof:

http://ngs.no.coocan.jp/doc/wiki.cgi/datapack?page=1%BE%CF+M...

"4. PCM
 PCMの録音・再生機能を標準搭載しました。これにより、従来のFM音源による音楽だけでなく、人の声やリアルな効果音の録音・再生が可能になりました。"

(translation)
"4. PCM
 recording and playback capabilities of PCM has been a standard feature. As a result, not only the music of the conventional FM sound source, is now possible to record and playback of human voice and realistic sound effects."

Your proofs are useless.

I expressed myself badly when I was say "The Turbo R PCM is not standard". I meant that PCM instructions are not the standard instructions from MSX-Basic but are extended instructions.

The fact that the PCM is the standard does not prevent these are instructions added for the PCM of the turbo R. These are extended instructions for the Turbo R's PCM. It's not instructions from the Basic 4.x.

In this case, SET SCROLL is not a standard BASIC instruction, and the same for all MSX2 additions. It's simply ridiculous to stay fixed by the 'CALL"!!!

No SET SCROLL is a standard BASIC instruction.
