indices 
A list containing one value for each index set of the given array
Return value

The following: 
public declarations
  myvar: dynamic array(set of integer,set of integer) of real
end-declarations
myvar(1,100) := 5.0
myvar(1,101) := 5.1
myvar(2,101) := 5.2
writeln('myvar(2,101)=',getarrayentry('myvar',[basicvalue(2),basicvalue(101)]))
produces this output: 
myvar(2,101)=5.2
Further information
