Example:

  ; Add one year to the current date 
    include "omdate.xin"
    process
      local stream ymdhms  ; current date
      local integer years-to-add initial {1}
      local stream incremented-date
      set ymdhms to now-as-ymdhms
      set incremented-date to add-to-ymdhms ymdhms years years-to-add
      output "Current date          = " || ymdhms || "%n"
      output "Current date + 1 year = " || incremented-date
  ; Result of this example:
  ;      Current date          = 20010214155655-0500
  ;      Current date + 1 year = 20020214155655-0500
