Imbedded SQL fails

[rob@xxxxxxxxx]

I have an SQL statement that fails in my RPG but not when ran
interactively.
     P FAXNEWAREA      B                   EXPORT
     D FAXNEWAREA      PI             3A
     D OldAreaCode                    3A   CONST
     D Exchange                       3A   CONST

     D* Local fields
     D retField        S              3A
     D CutDays         s             10i 0 inz(180)
     D* Based on information from Ken Shaw of Sprint, Chris Edwards
determined that we can safely
     D* change the area codes up to 6 months, (180 days), after the cutoff
to use new area codes
     D* becomes mandatory.  Exchanges should not be reused before then.  In
other words, when the
     D* exchange 347 split off from area code 219 into the new 260, we
figure that we can assume
     D* that the old 219 area code will not start reusing 347 for a new
city until after this
     D* time has passed.
     D ac              s              5a
     D ex              s              5a

      /free
       ac=apos + OldAreaCode + apos;
       ex=apos + Exchange + apos;
      /end-free

     C/EXEC SQL
     C+ SELECT enew into :retField
     C+ from exfile join acfile on eold=cold
     C+ where enew=cnew and days(curdate())-days(
     C+ date(cepmth concat '/' concat cepday concat '/' concat cepyr))
<:CutDays
     C+ and eold=:ac and eexc=:ex
     C/end-exec

      /free
       Select;
       When sqlcod<>0;
        retField=*blanks;
       Endsl;
       return retField;
      /end-free
     P FAXNEWAREA      E

When ran in debug the values of the fields are:
retField=*null
CutDays=180
ac='219'
ex='347'
sqlcod=000000100

>From the joblog:

SQLCOD = 000000100.

This is in a service program called by another program
Service program was created
CRTSQLRPGI OBJ(ROUTINES/SRVPGM) SRCFILE(ROUTINES/QRPGLESRC) COMMIT(*NONE)
OBJTYPE(*MODULE) TGTRLS(V5R1M0) DBGVIEW(*SOURCE)
then

           ACTGRP(SRVPGM) SRCFILE(ROUTINES/QSRVSRC)

But the following works interactively
SELECT enew
from exfile join acfile on eold=cold
where enew=cnew and days(curdate())-days(
date(cepmth concat '/' concat cepday concat '/' concat cepyr))<180
and eold='219' and eexc='347'
