Can't debug (with source view)

Hi,

I'm trying to get source level debugging to work for a C program on a V5R1
machine.  I've been at it for awhile with no success.  In checking the
manual, all I should have to do is to specify DBGVIEW other than *NONE, and
perhaps an OPTION such as *SHOWUSR.  But it doesn't work for me.  I always
get the 'source not available' message from STRDBG.

I must be making some simple error -- I just can't see what it is.  If you
could give me some pointers, I would be grateful.

Here is how I create the C modules.  Note that my source is on the IFS.
           CRTCMOD    MODULE(&LIB/&MODULE) SRCSTMF(&MODSRC) +
                          OUTPUT(*print) DBGVIEW(*ALL) DEFINE(STDC +
                          AS400) SYSIFCOPT(*IFSIO) OPTION(*SHOWUSR)

Here is how I create the program that I wish to debug:
           CRTPGM     PGM(&LIB/XMAKE) MODULE(INCLUDE LIST MAIN +
                        SUBS VAR WILD POPEN) ENTMOD(MAIN) +
                        DETAIL(*FULL)

Here is the error screen from STRDBG (And it's driving me crazy!):
                             Display Module Source

   (Source not available.)


Below is the relevant section of DSPPGM.  Note that for the modules, it
indicates DEBUG is *YES, and OPTIMIZATION LEVEL is *NONE for each.
