ReadInt PROC Reads a 32-bit signed decimal integer from standard input, stopping when the Enter key is pressed. Show Call args: None
Return args: If OF=0, EAX = valid binary value, and SF=sign.
If OF=1, EAX = 0 (invalid input)
Example:
.data
intNum DWORD ?
promptBad BYTE "Invalid input, please enter again",0
.code
read: call ReadInt
jno goodInput
mov edx,OFFSET promptBad
call WriteString
jmp read ;go input again
goodInput:
mov intNum,eax ;store good value
Notes: To read an unsigned integer, use the ReadDec procedure.To read in hexadecimal, use the ReadHex procedure. Recommended textbook solutions

computer science Verified answer computer science A page-replacement algorithm should minimize the number of page faults. We can achieve this minimization by distributing heavily used pages evenly over all of memory, rather than having them compete for a small number of page frames. We can associate with each page frame a counter of the number of pages associated with that frame. Then, to replace a page, we can search for the page frame with the smallest counter. a. Define a page-replacement algorithm using this basic idea. Specifically address these problems: i. What is the initial value of the counters? ii. When are counters increased? iii. When are counters decreased? iv. How is the page to be replaced selected? b. How many page faults occur for your algorithm for the following reference string with four page frames? 1, 2,3, 4, 5, 3, 4, 1, 6, 7, 8, 7, 8, 9, 7, 8, 9, 5, 4, 5, 4, 2. c. What is the minimum number of page faults for an optimal page replacement strategy for the reference string in part b with four page frames? Verified answer Recommended textbook solutions

Mechanically speaking, the CALL instruction pushes its return address on the stack and copies the called procedure's address into the instruction pointer.
