Designing the Bank

Here the layout of the bank and the meaning of each word is defined. Every constants bank will start with a 30 word fixed length Database header, in addition to the ZEBRA overhead. So the bank looks like this:-

Start of bank

  $\sim$ 10 ZEBRA header words


Lxxxx 		 $\rightarrow$ Status word of bank


Start of Database Header


30 words of Database header


LDxxxx 		 $\rightarrow$ Last word of Database Header


LDxxxx+1		 $\rightarrow$ Start of User data

A total of 30 words overhead may sound a lot but there won't ever be many of these banks in memory simultaneously.

Keep the structure of the bank simple; its format has to be describable using a ZEBRA bank format string see (below). As the format specifier can become complicated for arbitrary combinations of data types, the user should try to group the data in a newly created titles bank so as to simplify the format.
