1. Which MFT manual?
2. TSO started as an OS/360 option for MVT, not for MFT.
>1. Every task(like a job-step) has a TCB, correct?
The job-step has more than one task, each of which has a TCB.
>Is the *ASCB* the same as *TCB*?
No. There is one ASCB per address space, and an address space normally
has multiple tasks.

In what manual? In MFT there is no ASCB, and in MVS there are multiple
ready queues, one of which is a queue of ready address spaces.

The details have changed, but the basic concept is the same.
