I am looking at a GTF trace of a multiuthreading system calling COBOL programs
compiled with THREAD.

I am seeing task switching to support the LOAD of a called program, i.e., the
calling program is running on TCB A but when it issues a call the LOAD SVC
comes from a different TCB.

Also, if I understand the manuals correctly, the WORKING-STORAGE section
outlives the TCB that originally invoked the program.

I am not finding a manual that describes the processing or possible gotchas. 

Can someone supply a pointer?
