ZBOOK provides facilities to create (at execution time) memory blocks of variable lengths, manage them and perform the following operations on them:

• create a block
• increase or decrease size of block
• set block to zero
• drop or delete block
• write block to file
• read from file
• print contents of block

Using ZBOOK, the total size of all blocks together cannot exceed the dimension of the array specified in the user's Fortran program. Using a subpackage YBOOK in connection with HBOOK (Y250), however, dynamic allocation of the total space is possible.
