####### FILE: MasterControl.ksh
#######
####### DESCRIPTION: Starts a DataStage MasterControl type job passing
#######              all runtime parameter values
#######
#######
####### Date       Version   Developer      Description
####### ---------- --------- -------------- ------------------------------------
####### 2002-05-15 1.0       Ken Bland      Initial release
####### 2002-06-27 2.2       Ken Bland      FileSetDate/ProcessDate modifications
####### 2002-07-10 2.2       Steve Boyce    Added ProcessDate as 14th parameter
####### 2002-08-16 2.3       Steve Boyce    Now calls stored procedure
#######                                     GET_NEW_BATCH_NBR in datastage schema
#######                                     instead of deriving it and inserting
#######                                     here.
#######                                     Uses comSQLPlus.ksh and comPLSQL.ksh
#######                                     instead of SQLPlusStub.ksh.ksh
