# Bits and Bytes

183 When debugging a program in FAST mode, the constant jumping of the picture as you move the cursor is annoying. Try this:

Bring the line cursor (>) next to the faulty line.  
CLS  
EDIT (Shift 1)

These operations will bring the faulty line to the bottom of an empty screen. Only the faulty line, and not the whole screen will flicker. A good improvement, not mentioning the added speed of the cursor movement.

184 To adjust a tape recorder’s volume or to verify that a program is loading properly, simply stop the tape recorder a few seconds after you have begun to load a tape. The computer will either crash, which means the program was loading correctly; or it will continue in a search pattern, which means there was a problem with either low volume or the title.
