A small example program and prj file are attached.

I think the IDynStr interface rates up there with Super Crunchy Peanut
Butter on pancakes, too bad there is not any documentation.

Project file follows at the end of the code:

teststr.clw:


    program

  include('dynstr.inc'),once

    map
      ShowCStr(*cstring)
      ShowStr(string s)
      main()
    end


DynQ    queue
dStr      &IDynStr
        end
x long
strVar   string(50)
holder   &cstring


  code
  main()
  return


main procedure()

  code

  strVar = 'This is another string'

  DynQ.dStr &= NewDynStr()
  add(DynQ)
  DynQ.dStr &= NewDynStr()
  add(DynQ)
  
  get(dynQ, 1)
  dynQ.dStr.cat('This is the first string')
  get(dynq, 2)
  dynQ.dStr.cat(strVar)
  
  loop x = 1 to records(dynq)
    get(dynq, x)
    message('just show the string in a loop ||' & dynq.dstr.str())
  end
  
  get(dynq, 1)
  ShowStr(DynQ.dStr.CStr())
  get(dynq, 2)
  ShowStr(DynQ.dStr.CStr())

  get(dynq, 1)
  ShowCStr(DynQ.dStr.CStr())
  get(dynq, 2)
  ShowCStr(DynQ.dStr.CStr())

  get(dynq, 1)
  DisposeDynStr(dynq.dStr)
  get(dynq, 2)
  DisposeDynStr(dynq.dStr)
  free(dynq)
  return

ShowCStr procedure(*cstring s)

  code
  message('inside procedure with a *cstring parameter || ' & s)
  return

ShowStr procedure(string s)

  code
  message('inside procedure with a string parameter || ' & s)
  return
