[Coco] USRx() and adding more parameters?

The BASIC ROM has the USR function:

DEF USR0=&H3F00

A=USR0(42)

It accepts one parameter.

Since it jumps from BASIC into the USR assembly, couldn’t that code just parse a “,” and more numbers, allowing it to accept whatever needed to be passed in?

A=USR0(1,2,3,4)
