Here's a rough summary of the differences between the
different debug views:

*NONE: No debugging possible.  Not very useful.

*STMT: You can do debugging, but you need a hardcopy
       of the program listing on your desk.

*SOURCE: The debugger shows the source file used to
       compile your program.  But, your source files
       need to be on the same system that you're
       debugging on.

*COPY: Like *SOURCE, but /COPY members can be viewed
       as well.

*LIST: The program object actually contains the compile
       listing, so you can debug on any system.  This
       is the most flexible, but obviously, the cost is
       very large program objects.  (TANSTAAFL)

*ALL:  The tables for *SOURCE, *COPY, and *LIST views
       are all included and you can choose which view
       to use while debugging.  Press F15 while
       displaying the module source.

There is no performance difference when using any
DBGVIEW option.  The debug information is used only
when you're debugging.
