XPLINK considerations

Note:
  1. The runtime options you specify will apply to all of the subroutines that are called by (call_sub) function. This includes options such as XPLINK. Therefore, all of your subroutines must have the same characteristics and requirements needed for these runtime options.
  2. If this is a non-XPLINK sub environment, then do not allow an XPLINK subroutine to be added to the table.
