A REXX program (or REXX EXEC) called DEMO is stored in the partitioned dataset TBISUSR.REXXCRS.EXEC. Execution is possible...
... via the TSO command: EXEC 'TBISUSR.REXXCRS.EXEC(DEMO)' EXEC, without any
... only after allocation of the partitioned dataset TBISUSR.REXXCRS.EXEC to the DD
... via the TSO command: CALL 'TBISUSR.REXXCRS.EXEC(DEMO)', without any additional
... only after compilation to COBOL, and via the TSO command:
Indicate what is not correct in a REXX program.
A REXX clause can be coded in uppercase, lowercase or mixed case.
Multiple instructions can be coded on 1 line, as long as they are separated by a ','
A REXX program should start with a comment clause /* REXX */
Continuation of REXX instructions is achieved by using a ',' as a continuation indicator
Complete correctly: When defining a variable in REXX, one can use up to 250 characters to name the variable. The initial value will be...
all blanks
NULL value
name of the variable in the same (mixed) case as the name.
name of the variable in uppercase
Consider the following: name = 'John' number1 = number2 number2 = 5 Which of the following REXX expressions will generate an error?
10 / number1
name || 'number2'
number2 * 3
name > number2
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:
output on the terminal: result = 2 3 5
output on the terminal: result = 3 2 1
output on the terminal: result = var_3 var_4 var_5
the program will terminate with an error
Complete correctly: The EXIT clause ends...
Ia loop unconditionally and continues with the next clause after the loop
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.
a loop and EXEC unconditionally, returns to the caller of the EXEC and provides a return code.
a loop and EXEC unconditionally, returns to the caller of the EXEC, but doesn't provide a return code.
To receive input from the screen, we use the command:
READ
PULL
ACCEPT
RECEIVE
Indicate the correct statement: REXX functions consist of a function name, immediately followed by its arguments coded between parentheses and separated by commas.
This is only true if there are arguments, otherwise the parentheses must be excluded.
This is also true if there are no arguments, but the parentheses can be omitted.
This is also true if there are no arguments, the parentheses must be included.
This is always true, since there are no functions without arguments.
Given that var_1 = 'Abc123', what is the result of DATATYPE(var_1,N)?
'123'
'Abc123'
