We would like to know how to past a link list created using NewList command as a parameter in a procedure call. Also we would like to know how to modify the link list inside the procedure call.

example:

Code: Select all

Structure mystruct
  data1.l
  data2.l
EndStructure

NewList mylist.mystruct()

Procedure myproc(*listptr)
  AddElement(listptr())
  listptr()\data1 = 25
  listptr()\data2 = 30
EndProcedure

somewhere in the program we call myproc procedure passing the link list

Code: Select all

  
myproc(@mylist)

Executing this give us this error:

listptr() is not a function, an array, or a linked list

NewList mylist.mystruct()  

Procedure myproc() 
AddElement(mylist()) 
mylist()\data1 = 25

Not possible to add an Element using a pointer.
This is possible:

Code: Select all

Structure MyStruct
  NumericID.l
EndStructure

NewList Original.MyStruct()
NewList TheCopy.MyStruct()
AddElement(Original())
AddElement(TheCopy())

Original()\NumericID = 10

Procedure CopyListItem(*Source.MyStruct, *Destination.MyStruct)
  *Destination\NumericID = *Source\NumericID
EndProcedure

CopyListItem(@Original(), @TheCopy())

Debug TheCopy()\NumericID
