RE:bug in loan.c
In looking over the code, I believe I have discovered the problem
with the perceived bug.
If on the command line you enter the month as a alpha string, March,
the program prints a schedule from january of the specified year.
However, in looking at the code, it expects the month to be a number
between 1 and 12. If you enter 3 instead of March, the program runs
and prints the schedule correctly. The followinf 2 lines of text
illustrate the command line arguments in both the correct and incorrect
formats and the results.
