Working with lists

Description

A series of examples showing some of Mosel's list handling functionality:

definining lists and initializing lists with values (listinit.mos)
enumeration and reversal of lists (listenum.mos)
operators on lists (listops.mos)
enumeration and reversal of lists (listenum.mos)
list access functions (merging two ordered lists, listmerge.mos)

Further explanation of this example: 'Mosel User Guide', Section 8.4 Initializing lists, Section 8.5 Working with lists

model "Reversing lists"

 declarations
  K,L: list of integer
 end-declarations
 
 L:= [1,2,3,4,5,6,7,8,9,10] 

! Standard enumeration
 forall(i in L) writeln(i)

! Enumeration in inverse order:
 ! 1. Splitting off the last list element
 K:=L
 while (K <> []) writeln(getfirst(splittail(K,1)))

 ! 2. Reversing the list itself
 reverse(L)
 writeln("Reversed: ", L)
 
 ! 3. Reversed copy of the list
 K:=getreverse(L)
 writeln("Reverse once more: ", K, L)
