MAXIMUM dobj.
For every WRITE statement which after execution of the statement MAXIMUM (not allowed in classes) writes the content of data object dobj to a list on any list level, implicitly the maximum value of all output values of obj since the execution of MAXIMUM with WRITE is determined and assigned to a data object MAX_dobj.
The statement MAXIMUM declares the global data object
MAX_dobj with the same type as
dobj. For dobj you can specify all data objects
that can be written to a list using WRITE. The statement MAXIMUM must not be positioned within a
procedure and may occur only once in every program.
