Attempting to watch individual elements of global arrays in the Debug
window may result in the message "Incompatible operands" being
displayed. This problem only occurs when a Program List is created
containing more than one C module.

The following steps illustrate the problem:

1. Create two C modules similar to the ones below and add them
   to a program list.

          TEST.C                         DUMMY.C
    ------------------                -------------

    #include<string.h>                #define dummy

    char str[80];

    void main(void)
    {
         strcpy(str, "Hello World");
    }

2. Rebuild the application with debug (CodeView) information.

3. Trace through the program by pressing F8.

4. Enter str and str[0] into the Watch (Debug) window.

The following lines will be displayed in the Debug window:

   str : <Cannot display>
   str[0] : <Incompatible operands>

Microsoft has confirmed this to be a problem in QuickC versions 2.00
and 2.01. The problem does not occur in versions 2.50 and 2.51.
