The ISML function hasElements() allows you to check whether an iterator stored in the pipeline dictionary contains any elements. This is particularly useful before looping through an iterator using a ISLOOPstatement. If your iterator contains a number of elements different from 0, the function returns true, otherwise false.


The functions hasElements()and hasLoopElements()are synonyms.


hasElements( <ISML variable identifier> )


<ISIF condition = "#hasElements(Basket:Offerings)#">Your basket contains:
  <ISLOOP iterator = "Basket:Offerings">
    <ISPRINT value = "#Offerings:Name#"><BR>
  <!-- Your basket contains nothing --!>
