Subject: [PATCH] Fix infinite loop

CID 176641:  Control flow issues  (STRAY_SEMICOLON)
A "while" statement with no block followed by a stand-alone block
is suspicious.

CID 176639:  Program hangs  (INFINITE_LOOP)
If "dx > 64L" is initially true then it will remain true.

Fixes a bug introduced in 8c31f75fd31d2d83de557c0d5fb15edb384f8933.
