User functions/uVision3

Ok, let's go about this a different way.

Here is a stripped-down version of a much more complex C
program, running on a Si Labs C8051F046:
>
> /* * * * * * * * */
> /* BEGIN t1.c    */
> /* * * * * * * * */
>
> unsigned char t1(unsigned char k);
>
> /* ========================== */
> /* main() routine             */
> /* ========================== */
>
> void main (void) {
>   unsigned char i, j;
>
>   for(;;) {
>     for(i=0; i<3; i++) {
>       j = t1(i);
>     }              /* Line 17 */
>     i=0;           /* Line 18 */
>   }
> }
>
> /* ========================== */
> /*   void t1(unsigned char i) */
> /* ========================== */
>
> unsigned char t1(unsigned char k) {

> /* * * * * * * * */
> /* END t1.c      */
> /* * * * * * * * */

At its essence, main() passes an argument, i, to function
t1(). Then t1() performs some math on the parameter received
and returns a value used by main().  This compiles, links,
and produces predicted output with my Keil simulator, or
running on the target hardware under Si Labs' debugger DLL.

But the amount of data in the real problem is much too
large to examine by hand, so I wish to automate the test
process with a user function, as described in the 
Getting Started with uVision2, Users Guide 02.2001, p.
137 and assorted other places. Here's what I came up with,
stored in script t1.ini:
>
> /* * * * * * * * */
> /* BEGIN t1.ini  */
> /* * * * * * * * */
>
> FUNC void t1a(void) {
>
>     printf("%3d %3d\n", i, j);
> }
>
> FUNC void t1b(void) {
>
>   exec("log > t1.log");
>   exec("bs \\TestClkVRef00\\17", 1, "t1a()");
>   exec("bs \\TestClkVRef00\\18", 1, "_break_=1");
>   exec("G");
>   while(_break_!=1)
>     ;           /* Wait until simulation stops */
>   exec("log off");
> }
>
> /* * * * * * * * */
> /* END t1.ini    */
> /* * * * * * * * */
>

User function t1a() prints present values of automatics i &
j, inside the "for(i=0; i<3; i++)" loop of main().  To have
them in scope, I set a breakpoint on the 'close curly
bracket' I have earmarked "Line 17" in a comment in the
source file.  This also works without a hitch.

But I'm still dissatisfied with the amount of keyboarding I
have to do, so I create function t1b() to automate it even
more.  Function t1b():
  - Opens a log file (t1.log) to capture my output for later
    use;
  - Sets the breakpoint I earlier defined manually on line
    17, to print the data.  According to my User's Guide,
    if I attach a command to my breakpoint, the
    debugger/simulator only breaks long enough to execute
    that command, so I just call the previously-debugged
    user function t1a() here, to print my results;
  - Sets another breakpoint on line 18 (which is outside the
    "for(i=0; i<3; i++)" loop), at which point I know my test
    app is done, and I want to close the log file.
  - Issues a "GO" command;
  - According to earlier posts to this forum, this script
    will continue to run on my host workstation, independent
    of the execution/breakpoint behavior of my target
    hardware, so I tell it to monitor the _break_ system
    variable, which I know will be set to 1 when my target
    breaks on line 18 of the target app.
  - Terminates capture of output to the log file, so I can
    look at it; import it into Excel, etc.

The trouble is, when I try to "include" this script into
uVision3, it crashes in the second function, on the line
that defines the first breakpoint:

  . . . .

so function t1b() never gets defined.

- If you parse the diagnostic, it appears to take issue with
  a badly defined union or structure on my part.
- If you examine my source file and script, you will find no
  attempts to define structures or unions.
- In fact you will not even find a period or '->' in either
  place.

I am stymied.  Can anybody translate this to English?
