The code is in error. The print string service 4 would send the bytes
starting at result to the monitor.
But these bytes encode 35 using 32-bit two's complement.
They are not the bytes for ASCII characters.

The example program reads in an integer, presumed to be a number of ounces, then writes out the equivalent number of pounds and ounces.
As is often the case, input and output dominate the program. The actual calculation is hard to find.
The program prints "Pounds" and "Ounces" on separate lines. Change the program so that they are printed on one line.
