(1) The search direction "Forwards" can be selected via the "SURI=V" block parameter
assignments. If the parameter is not assigned, i.e. "SURI = ' ' ", the search direction
"Forwards" is also defined internally.
(2) With the parameter assignments, "MAGA" > 0 and "MAGE" = 0, all chained magazines
are searched, starting at "MAGA". The search is not completed until
– the required free magazine area has been found,
– the searched magazine is not assigned to any further, chained magazine,
– the chained magazine corresponds to the magazine specified in the parameter
"MAGA".
Note that all magazines included in the search key must have the same
machine data setting (without configuration) if the search for an empty
location extends over several magazines.
