I have a problem getting my assembly program designed to get the first 47 numbers of the fibonacci series to output to a file. I'm not getting any errors except for when opening command window. This is the exact question on my homework problem if this helps :
Using Programming Exercise 6 in Chapter 4 as a starting point, write a program that generates the first 47 values in the Fibonacci series, stores them in an array of doublewords, and writes the doubleword array to a disk file. You need not perform any error checking on the file inputoutput because conditional processing has not been covered yet. Your output file size should be 188 bytes because each doubleword is 4 bytes. Use debug.exe or Visual Studio to open and inspect the file contents, shown here in hexadecimal.
