How do I display the compiler error window?

[ND in WV]

All I have showing is the editor window. After it compiles it will highlight a
statement in red, but I have no clue what the error is. I am using the ANSI C
compiler

The "Compiler" tab at the bottom lists filtered compiler and linker messages
that when clicked-on will highlight the associated source code. The "Compile
Log" tab contains the complete unfiltered log; this is what you need to post
if you need further assistance.
