Setting Breakpoints for Debug



Hi,

Appearently, breakpoints can only be set for functions which
are loaded from a file. When I try to set a breakpoint for a
function which is defined directly in the current Maxima session
using the command ":br test", I get the Message:

No line info for $TEST

Are breakpoints in any way bound to files or has a function
to be treated in a special way to enable breakpoints?
Setting a breakpoint for a function which has been loaded via
"load" works fine:

Bkpt 2 for test (in d:/maxima/test.mac line 2)

Is there a possibility for breakpoints in functions,
which are not loaded via "load" too?

Thanks in advance,
