// Standalone utility to issue local and global SEQNOs.

// Invocation: seqno=`allocate_seq_no.exe <table-name> { <requireGlobal> <dbNo> } | tail -1`

// Where:-
//   tableName       in    The table for which the SEQNO is required.
//   requireGlobal   in    The type of SEQNO required:-
//                           > 0  Must be global
//                           = 0  Must be global if supplied dbNo is authorising
//                                and table isn't temporary otherwise local
//                           < 0  Must be local
//   dbNo            in     The entry in the cascade for which the SEQNO is required
//
//   seqno           out    The allocated SEQNO (or 0 if unable to allocate one)
//
//   | tail -1       Is need to filter the output and keep only the last line.
