compiling sql rpg

I'm a novice with sql in rpg.  I inherited a project from a contractor
who's no longer with us.  I modified an sqlrpgle program she wrote to
add a screen option, didn't modify any of the sql.  When I compile it
out of WDSCI the compile fails with a host of duplicate identifier
errors.  In the compile a bunch of new code appears with right hand
comments that say "SQL".  The added code is the sql communications area,
a few anonymous data structures, and api calls following every sql
statement group.  When I compile it from PDM it works fine. 

I wouldn't be surprised if it were a difference in the compile parms,
but I haven't found it yet.  What do I need to change?

Thanks
