b. No answer is correct

c. DECI

d. ADDSP

An assembler translates from the Asmb5 level to:

Select one:

a. Operating system level

b. Microcode level

c. No answer is correct

d. Instruction set architecture level

Solution

The assembly instruction implemented at the OS4 level is:

Answer) c. DECI ( Decimal Input trap)

instructions available at assembly language level even though they are not (directly) available at the machine language level.

In order to Represent operations handled by the operating system includes

NOPn: unary no operation trap
NOP: non-unary NOP
DECI: decimal input trap
DECO: decimal output trap
STRO: string output trap

An assembler translates from the Asmb5 level to

Answer ) option a. Operating system level

The assembly language level is an intermediate step between high order language and the machine language of a particular processor.Programs at the HOL6 level are usually compiled to level Asmb5 , then translated(assembled) to machine language.source code can be written in assembly language
