Compile, Delete, Purge and Load

Apologies to all for going off prematurely on this e-mail, thick fingers
today...

 
Folks
 
I am developing away in Erlang. I have a setup routine that 
creates an mnesia database and does some things to it, gets 
tables set up right and clean. I step through my code in the 
debugger and make changes, etc, etc.

In order to speed things up and not have to recreate the 
environment I have written a little routine that basically 
does the following for all my modules:

   Results999_G =
compile:file("/opt/erlang_apps/swarm/lib/html_fragments-V1/src/sms_shim.erl"
, [debug_info, {outdir,
"/opt/erlang_apps/swarm/lib/html_fragments-V1/ebin"}]),
    io:fwrite("G) sms_shim: ~30s~n", [io_lib:write(Results999_G)]),

    code:delete(sms_shim),
    code:purge(sms_shim),
    code:load_file(sms_shim),

When I haven't loaded the debugger on a particular module this is fine and
the new version is loaded and ready to roll, but when I have looked at a
module in the debugger this routine tells me:

	module sms_shim must be purged before loading

and I have to halt the Erlang shell, restart it and reinitialise everything
again.

How do I get a 'debugged' function to purge?

Gordon
