Chapter 10, Problem 1P
Program Plan Intro
a.
“MOV” Command:
- “MOV” instruction or command is used to copy the contents from source to destination address.
- The original content remains unchanged in the source location and the duplicate contents are stored in the destination address.
- “MOV” command copies the files or data from source to destination address as long as rung is true.
“N7:13”:
- “N7:13” is an integer word address.
- “N7:13” represents a single word and word number 13 in an integer file 7 where N represents an integer type of file.
Program Plan Intro
b.
“N7:112”:
- N7:112 is an integer word address.
- N7:112 represent a single word and word number 112 in an integer file 7 where N represents an integer type of file.
“MOV” Command:
