Scroll Window Utility

[GCHarder]

Here's a nice little scrolling windows utility from ZX Computing.

The MC for this app worked fine, however, the BASIC listing contained many bugs so I've redone it.
Most notably line 290 POKE B+30-L, CODE K$ should be 290 POKE B+30+L,CODE K$. The former is almost always guaranteed to crash the program. There were other bugs as well.
