What is Banker?
===============

*Banker* is a G data bank maker.  It creates G data banks without going through *G7*.  It particularly is suited for making large G data banks, since compressed *Banker*-generated data banks are NOT bounded by the rather limited number of series allowed with any *G7*-generated workspace bank.  With compressed banks that are built by *Banker*, your G-bank literally can include millions of series and the size of your hard disk becomes the constraint.

*Banker* makes both hashed (.HBK, .HIN) and compressed (.CBK, .CIN) G banks.  However, users strongly are encouraged to produce the hashed bank, as it now is the standard data bank that Inforum creates and maintains.
