Unidentified identifier in Watches tab (debugger)

[Duane B]

Hello fellow Picsters,

What does one have to do to add a variable expression to the 'Watch' tab of the debugger using the ICD-U40? Here in my code:

#include <16f877.h>
#device *=16 ICD=TRUE
#use delay (clock=4000000)


void main()
{

byte q = 0;

while (1)
{
q++;
delay_ms(1000);
}
}

When I click the '+' in the Watch tab and enter 'q' as the expression to watch, I get this:

ERROR #12: Unidentified identifier

Any suggestions as to what I'm doing wrong?

Thanks,
Duane

<font face="Courier New" size=-1>I just experimented with this, and before I run my target program, I get that error for all non global variables. After I run the program and hit "stop" from the debugger (or a breakpoint) the error message disappears and the proper value
is in the watch.

I didn't run your program, however.

Hope that's somewhat helpful.

Well, that seemed to be the problem.

Thanks,
Duane

I guess, if one thinks about it, it makes sense. The non-global variables have not yet been assigned memory locations because they haven't been created yet, so how could the debugger know about them?
