Q210 Dynamic Memory Management

Routine ID: Q210
Author(s): R. Brun, F. Carena, M. Hansroul, H. Grote, J.C. Lassalle, W. Wojcik	Library: PACKLIB
Submitter:	Submitted: 15.09.1978

OBSOLETE

Please note that this routine has been obsoleted in CNL 219. Users are advised not to use it any longer and to replace it in older programs. No maintenance for it will take place and it will eventually disappear.
Suggested replacement: ZEBRA (Q100)

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.

Structure:

SUBROUTINE package
User Entry Names: ZBOOK

Usage:

See Long Write-up.
