  1. ... via the TSO command: EXEC 'TBISUSR.REXXCRS.EXEC(DEMO)' EXEC, without any

  2. ... only after allocation of the partitioned dataset TBISUSR.REXXCRS.EXEC to the DD

  3. ... via the TSO command: CALL 'TBISUSR.REXXCRS.EXEC(DEMO)', without any additional

Indicate what is not correct in a REXX program.
technology mainframe

  1. A REXX clause can be coded in uppercase, lowercase or mixed case.

  2. Multiple instructions can be coded on 1 line, as long as they are separated by a ','

  3. A REXX program should start with a comment clause /* REXX */

  4. Continuation of REXX instructions is achieved by using a ',' as a continuation indicator

Correct Option: B

Complete correctly: When defining a variable in REXX, one can use up to 250 characters to name the variable. The initial value will be...

  1. all blanks

  2. NULL value

  3. name of the variable in the same (mixed) case as the name.

  4. name of the variable in uppercase

Correct Option: D

Consider the following: name = 'John' number1 = number2 number2 = 5 Which of the following REXX expressions will generate an error?

technology mainframe

  1. 10 / number1

  2. name || 'number2'

  3. number2 * 3

  4. name > number2

Show answer
Correct Option: A

AI Explanation

To determine which of the given REXX expressions will generate an error, let's go through each option:

A. 10 / number1 - This expression will generate an error because number1 has not been assigned a value. It is attempting to perform division with an undefined variable.

B. name || 'number2' - This expression will concatenate the value of the variable name with the string 'number2'. It will not generate an error.

C. number2 * 3 - This expression will multiply the value of the variable number2 by 3. It will not generate an error.

D. name > number2 - This expression will compare the value of the variable name with the value of the variable number2. It will not generate an error.

Therefore, the correct answer is A. This expression will generate an error because number1 has not been assigned a value.

Consider the following clauses: var_1 = 2 var_2 = 3 IF var_1 = var_2 THEN var_3 = var_1 var_4 = var_2 var_5 = var_2 + var_1 ELSE var_3 = var_2 var_4 = var_1 var_5 = var_2 - var_1 SAY "result = " var_3 var_4 var_5 What will happen when this REXX is executed:
technology mainframe

  1. output on the terminal: result = 2 3 5

  2. output on the terminal: result = 3 2 1

  3. output on the terminal: result = var_3 var_4 var_5

  4. the program will terminate with an error

Correct Option: D

Complete correctly: The EXIT clause ends...
technology mainframe

  1. Ia loop unconditionally and continues with the next clause after the loop

  2. IF var_1 = var_2 THEN var_1 = var_1 + a loop and EXEC unconditionally, but doesn't return to the caller of the EXEC.

  3. a loop and EXEC unconditionally, returns to the caller of the EXEC and provides a return code.

  4. a loop and EXEC unconditionally, returns to the caller of the EXEC, but doesn't provide a return code.

Correct Option: C

To receive input from the screen, we use the command:

technology mainframe

  1. READ

  2. PULL

  3. ACCEPT

  4. RECEIVE

Show answer
Correct Option: B

AI Explanation

To receive input from the screen, the correct command is typically "ACCEPT" rather than "PULL". The "ACCEPT" command is commonly used in programming languages like COBOL or RPG to read input from the user.

Option A) READ - This option is incorrect because "READ" is not a command commonly used to receive input from the screen. Option B) PULL - This option is incorrect because "PULL" is not a command commonly used to receive input from the screen. Option C) ACCEPT - This option is correct because "ACCEPT" is commonly used to receive input from the screen in programming languages like COBOL or RPG. Option D) RECEIVE - This option is incorrect because "RECEIVE" is not a command commonly used to receive input from the screen.

The correct answer is C) ACCEPT. This option is correct because "ACCEPT" is the command commonly used to receive input from the screen in programming languages.

Indicate the correct statement: REXX functions consist of a function name, immediately followed by its arguments coded between parentheses and separated by commas.
technology mainframe

  1. This is only true if there are arguments, otherwise the parentheses must be excluded.

  2. This is also true if there are no arguments, but the parentheses can be omitted.

  3. This is also true if there are no arguments, the parentheses must be included.

  4. This is always true, since there are no functions without arguments.
