Embedded SQL Problem

If anyone can help figure out what's going on, I'd appreciate it.  Here's
what's happening so far:
=================================================================================
Screen 1: User selects the reports they would like to print(Report 1,
Report 2, or Report 3)

<Enter Pressed>

(SQL RPG Program Begins)

If Report 1
callp PRCS_REPORT1
ENDIF

If Report 2
callp PRCS_REPORT2
ENDIF

If Report3
callp PRCS_REPORT3
ENDIF

start PRCS_REPORT1
SQLSTRING = 'DECLARE GLOBAL TEMPORARY TABLE.......'
/EXEC SQL
      PREPARE SQLCMD FROM :SQLSTRING
      EXECUTE SQLCMD
/END-EXEC
end PRCS_REPORT1

start PRCS_REPORT2
SQLSTRING = 'DECLARE GLOBAL TEMPORARY TABLE.......'
/EXEC SQL
      PREPARE SQLCMD FROM :SQLSTRING
      EXECUTE SQLCMD
/END-EXEC
end PRCS_REPORT2

start PRCS_REPORT3
SQLSTRING = 'DECLARE GLOBAL TEMPORARY TABLE.......'
/EXEC SQL
      PREPARE SQLCMD FROM :SQLSTRING
      EXECUTE SQLCMD
/END-EXEC
end PRCS_REPORT3

*INZSR BEGSR
C/EXEC SQL
C+ Set Option
C+     Naming    = *Sys,
C+     Commit    = *None,
C+     UsrPrf    = *User,
C+     DynUsrPrf = *User,
C+     Datfmt    = *iso,
C+     CloSqlCsr = *EndMod,
C+     Commit    = *none
C/END-EXEC
ENDSR

(SQL RPG Program Ends)
=================================================================================

I can run Report 1, 2, or 3 one at a time with no problems, but if I select
all 3 reports to print, the 1st report will print, but the program crashes
on the 2nd report.  Am I missing an SQL statement anywhere?  I'm only using
PREPARE and EXECUTE.

Thanks,

Frank
