SYMPTOMS
If you assemble the following program with MASM version 5.1 and examine the public label, TheProc, you will find an underscore prefixed to it. Another symptom of the problem may occurs during link time. The linker will generate the error L2029 unresolved external on public labels.
CAUSE
The space before the comma in the structure initialization of Data1 causes the problem to occur.
RESOLUTION
Removing the space before the comma in the structure initialization of Data1 will allow you to work around the problem.
STATUS
