XPLINK considerations

If the first program in the customer PreInit table is an XPLINK program, then an XPLINK environment will be initialized.
If the runtime options are passed as input and the XPLINK option is specified as XPLINK(ON), then an XPLINK environment will be initialized.
If neither of the above are true (the first program in the customer PreInit table is a non-XPLINK program and the XPLINK runtime option is off or not specified), then a non-XPLINK environment will be initialized.

Note: The runtime options you specify apply to all of the subroutines that are called by (call_sub_dp) function. This includes options such as XPLINK. Therefore, all of your subroutines must have the same characteristics and requirements needed for these runtime options.
