To receive input from the screen, we use the command:
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)?
What is the result of TRUNC(12.3456,3)?
Complete correctly: When calling a subroutine with the clause CALL 'SUBROUT1',...
the external subroutine SUBROUT1 will be executed, bypassing any internal subroutines.
the internal subroutine SUBROUT1 will be executed; external subroutines aren't called.
the internal subroutines will be searched for SUBROUT1; only if there isn't an internal one, the external SUBROUT1 will be executed.
an error will occur; subroutine names must never be coded between quotes.

Concerning the shielding of variables of an internal subroutine from the main EXEC part, which of the following is correct:
One can not shield variables in a subroutine from the main EXEC, only from other subroutines.
One can shield the variables by using the clause: CALL SUBROUT1 PROCEDURE
One can shield the variables by defining the start clause of a subroutine:SUBROUT1: PROCEDURE
One can shield the variables by defining the start clause of a subroutine: SUBROUT1: SHIELDED
