To pass commands to a specific host environment (ex. TSO), which clause must be used?

  1. HOST TSO

  2. HSTADDRS TSO

  3. ADDRESS TSO

  4. EXEC TSO

C Correct answer
Explanation

The ADDRESS clause in REXX directs commands to a specific host environment. ADDRESS TSO sends subsequent commands to the TSO environment. HOST TSO, HSTADDRS TSO, and EXEC TSO are not valid REXX syntax for this purpose.

AI explanation

In REXX, the ADDRESS instruction directs subsequent commands to a specific host command environment — e.g., 'ADDRESS TSO' routes commands to TSO rather than the default environment. This is the actual REXX keyword/clause; 'HOST TSO', 'HSTADDRS TSO', and 'EXEC TSO' are not valid REXX syntax and are simply invented distractors resembling the real keyword.
