I have a problem with a program I have written.  It is called as a rexx
function.  The first time the routine is called it nucxloads itself before
execution.  The routine has to be in the Nucleus because it calls
SQLINIT EXEC & RXSQL MODULE.  These programs load various routines into
memory (USER  AND!! TRANSIENT).  If I don't then when control is returned
my program aborts (it gets overwritten).

My problem now is:  when control is passed back from SQLINIT EXEC I get an
operation exception (in the user area!!).  Somehow control is being passed
back to a location in the user area..i.e. 208A4 even though my program
resides (should) at D000-E000.  Any Ideas as to what is going on?

Note:  I now call SQLINIT2 which is an exec which does a NUCXMAP and then
calls the REAl Sqlinit exec and then again does a NUCXMAP.  The map says
my program is still in the Nucleus.  after that the PGM dies!


Any suggestions?  I have tried everything I can think of.


Thanks!,
