you can examine and modify the contents of a
label. The .TFPLT function requires the JP.POK,
[1,2], or JACCT privilege.
Returns the last tape label termination code from
the tape label processor. It is recommended that
you use DEVOP. function .DFRES, because more
information can be returned by that function. The
return codes are:
