technology mainframe

  1. TRACE R

  2. TRACE ?R

  3. TRACE IR

  4. INTTRACE R

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the command used to activate the interactive trace in REXX.

Option A) TRACE R - This option is incorrect because the TRACE R command does not activate the interactive trace. Instead, it activates the trace for the execution of a REXX program.

Option B) TRACE ?R - This option is correct because the TRACE ?R command activates the interactive trace. The ? symbol is used to indicate an interactive trace in REXX.

Option C) TRACE IR - This option is incorrect because the TRACE IR command does not activate the interactive trace. Instead, it activates the trace for the execution of a REXX program.

Option D) INTTRACE R - This option is incorrect because the INTTRACE R command does not activate the interactive trace. Instead, it activates the internal trace for the execution of a REXX program.

The correct answer is B) TRACE ?R. This option is correct because it activates the interactive trace in REXX.
