The compiler is emitting debugging information when it builds your code
into a Palm application. However, the debug info isn't an exact match
to your code. One of the ways it varies is how it handles variable
scoping. The compiler emits info as is your variable always exists
within the function. The value may not be reliable until you execute
the code to initialize the value -- basically, the variable list that
the debugger sees is the union of all variables defined in the function,
not dependent on when the variable is "defined" by the language.
Since code can't change that value, except by accidental stack smash,
until the variable is defined, don't worry about it. If you're
concerned about seeing its value change, that isn't a problem, as the
space used for it is probably being reused by another variable that
doesn't have a lifetime that conflicts with it.
