//====================================================================
// Test program to exercise BASE36ADD in batch.
// Result values are written out to table BTB.
// Call with two parameters:
//  1) Starting value to increment,  e.g. '988'
//  2) Ending value, e.g. '992'
//  Examples:
//   CALL PGM(BTBR) PARM('988' '992')
//        Should write 31 records.
//   CALL PGM(BTBR) PARM('1B999999999999999998' '1CAAAAAAAAAAAAAAAAAD')
//        Should write 6 records.
// SQL error checking is functional but it is not production
// quality.  Do not copy!
