Memory management

The memory management package MZ of ZEBRA is fundamental to all other ZEBRA packages.

The ZEBRA package MZ derives from its predecessors:

• the ZEBRA data structure derives from the HYDRA data structure [3];
• the multi-store strategy derives from ZBOOK [4]

• ZEBRA bank format
• MZEBRA - initialize the ZEBRA system
• MZLOGL - change the MZ logging level
• MZSTOR - initialize a dynamic store
• MZDIV - create a new division
• MZLINK / MZLINT - initialize a link area
• MZWORK - allocate working space
• MZLIFT / MZBOOK - bank creation
• MZPUSH - alter the size of a bank
• MZREPL - connect replacement banks
• MZDROP - drop a bank and its dependents
• MZWIPE - reset complete divisions to empty
• MZGARB - garbage collection requested by the user
• MZXREF - set cross-reference between divisions
• MZIXCO - create compound division index
• MZFORM et al. - handle the I/O characteristic
