We use a function which can be used to initialize of list of strings or numbers.

Use it like :
	initcontainer("n",50)			--> returns a list of 50 lines from 1 to 50
	initcontainer("n",50,101)			--> returns a list of 50 lines from 101 to 150
	initcontainer("n",50,101,2)		--> returns a list of 50 lines from 101 to 199
(step 2)
	initcontainer("n",50,101,2,comma)	--> returns a list of 50 items from 101 to
199

	initcontainer("s",50,"Revolution")	--> returns a list of 50 lines each with
"Revolution"
	initcontainer("s",50,"Revolution",tab)	--> returns a list of 50 tab separated
'items' "Revolution"

This prevents re-scripting repeat loops again and again....


function InitContainer pKind, pNum
  if pNum <= 0 then return("")
  if pKind = "s" then put "t" into pKind
  put CR into lSeparator
  if (pKind = "t" and (the paramCount < 3 or the paramCount > 4)) or (pKind =
"n" and (the paramCount < 2 or the paramCount > 5)) then StopWithMessage
"Invalid number of arguments !"
  if pKind = "t" then
    put the param of 3 into lValue
    if the ParamCount = 4 then
      put the param of 4 into lSeparator
    end if
  else
    put 1 into lValue
    put 1 into lStep
    if the ParamCount >= 3 then
      if the param of 3 is a number then
        put the param of 3 into lValue
        if the ParamCount >= 4 then
          if the param of 4 is a number then
            put the param of 4 into lStep
            if the ParamCount = 5 then
              put the param of 5 into lSeparator
            end if
          else put the param of 4 into lSeparator
        end if
      else put the param of 3 into lSeparator
    end if
  end if
  if pKind = "n" then put "add lStep to lValue" into lAddStep
  else put "" into lAddStep
  put "" into lResult
  do "repeat pNum-1"&CR&\
      "  put lValue&lSeparator after lResult"&CR&\
      "  "&lAddStep&CR&\
      "end repeat"
  put lValue after lResult
  return(lResult)
end InitContainer
