[Oberon] System V5 - SYSTEM.Mod creation

[thomas.kral at email.cz]

Hi,

While I am still studying PO.Applications, chapters on compiler, I already noticed that modules often import low level routines from SYSTEM.

I can see from the sources how routines are referenced, but actually where are they defined and built into the Oberon system?

SYSTEM.BIT
SYSTEM.GET
SYSTEM.PUT
SPI
SYSTEM.LDREG
SYSTEM.REG
SYSTEM.ADR
SYSTEM.VAL

The above list may not be complete.
It also proves I am not a careful reader, but I saw  some pseudo SYSTEM module being initialised in ORB.Mod.

Many thanks Tomas
