Subject: [PATCH] Preserve PRCNT*

Here's what each program does:
 * **PRCNTDIF** - PeRCeNT DIFference
 * **PRCNTERR** - PeRCeNT ERRor

These two programs were written during my college prep physics class
during high school. They are a classic example of using my calculator
programming skills to avoid learning the rationale behind an
important formula for experiments. I simply didn't want to have to
worry about the formula, so I figured it out once and then let my
calculator take care of it from thereon and thenceforth.

However, though they are only three lines long, they demonstrate one
interesting insight into my development as a programmer. These programs
appears to be the first time that I did computation in the `Disp`lay
step in order to save a line or two of code. It demonstrates that (1) I
had started to figure out the expanded set of precedence rules that
govern expression evaluation in programming languages and (2) had begun
to exploit those rules to make my programs more concise and readable.
