1. ʾĀlep is the reconstructed name of the first letter of the Proto - Canaanite alphabet, continued in descended Semitic alphabet as Phoenician Aleph , Syriac 'Ālaph ܐ, Hebrew Aleph א, and Arabic ʾAlif ا.


Example 

eastbound(A) :-
   has_car(A,B).
[5/5]
eastbound(A) :-
   has_car(A,B), short(B).
[5/5]
eastbound(A) :-
   has_car(A,B), open_car(B).
[5/5]
eastbound(A) :-
   has_car(A,B), shape(B,rectangle).
[5/5]

[theory]
 
[Rule 1] [Pos cover = 5 Neg cover = 0]

eastbound(A) :-
       has_car(A,B), short(B), closed(B).

[pos-neg] [5]

output:

           Actual
        +          -  
     +  5          0         5 
Pred 
     -  0          5         5
 
        5          5         10

2. ABAP (Advanced Business Application Programming) - is a high-level programming language created by the German Software company SAP. It is currently positioned, alongside the more recently introduced JAVA.

Example 

AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_ebeln-low.
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      input  = s_ebeln-low
    IMPORTING
      output = s_ebeln-low.

  perform form_search_help.

  IF sy-subrc <> 0.
    CASE sy-subrc.
      WHEN 2.
        LEAVE TO SCREEN 1000.
    ENDCASE.
  ELSE.
    LOOP AT it_ebeln.
      IF sy-tabix = p_ebeln.
        s_ebeln-low = it_ebeln.
        EXIT.
      ENDIF.
    ENDLOOP.
  ENDIF.
3. Ada - is a structured, statically typed, imperative, wide-spectrum, and object-oriented  high-level computer programming language, extended from Pascal and other languages. 

Example

with Ada.Text_IO, Ada.Integer_Text_IO;
   use Ada;
   
   procedure Simple is
   
      type Integer_Pointer is access Integer;
      A,B: Integer_Pointer := null;
      C: Integer;
  
  begin
  
     A := new Integer;
     A := new Integer'(17);
  
     B := new Integer'(32);
  
     Integer_Text_IO.Get (Item => A.all);
     Integer_Text_IO.Put (Item => B.all);
  
     C := A.all + B.all;
  
     -- copy the value
     A.all := B.all;
  
     -- make an alias
     A := B;
  
     A.all := 49;
     Integer_Text_IO.Put (Item => B.all);
  
  end Simple;

4. ABC -  is an imperative general-purpose programming language  and programming environment developed at CWI,Netherlands by Leo Geurts, Lamber Meertens, and Steven Pemberton.

Example: 

HOW TO ADVENTURE:
    START
    GET command
    WHILE command <> "quit":
       OBEY command
       GET command
    FINISH

5. ALgae -  is an interpreted programming language for numerical analysis, a branch of mathematics. Its interactive interpreter is available under GPL. The language and its implementation were designed by Scott Hunziker and Mike Brennan starting in 1994.

Example 

 
# power:  raise `x' to the `n'-th power
power = function (x; n)
{
  local (y);
  y = x;
  while (n > 1)
  {
    y = y * x;
    n -= 1;
  }
  return y;
};

power (2; 8)?
power ([ 1, 2; 2, 3 ]; 4)?

comparison of ABC and ABAP

ABC is structured intend to be use instead BASIC, Pascal and CWK but ABAP introduced by JAVA somewhat similar to COBOL
