- An integrated editor for compilation, development and debugging- all very easy.

 

 

Starting Turbo prolog

 

c>PROLOG

 

Then the user-friendly editor appears as follows:-

 

Run      Compile      Edit     Options     Files   Setup    Quit
Editor Line1   Col1   Indent  Insert Work.pro		----Dialog-----
--------Message---------	--------Trace----------

Use first letter of Option or select with -> or <-

 

 

Create a Sample program

 

1.Select Edit mode & enter program

2.                      Enter text or corrections as necessary

3.                      Save the program to disk

4.                      Compile the program

5.                      Execute the program

 

Edit operations : REFER BOOK

 

Similar to Turbo pascal

 

SAMPLE TEST PROGRAM

Run      Compile      Edit     Options     Files   Setup    Quit
Editor Line1   Col1   Indent  Insert Work.pro /* SAMPLE TEST PROGRAM */ predicates      likes(symbol , symbol) clauses      likes(frank,sue).      likes(Harold,ruth).		----Dialog-----
--------Message---------	--------Trace----------

F1:Help F3:Search F4:Subst F5:Copy F6:Move F7:del F8:ExtEdit F9:ExtCopy F10:End

 

Starting to execute the program

To compile and execute the

program exit the editor using Esc

or F10. Then select the Run option

from the main menu.

 

If NO errors, then see the prompt

in dialog box as follows:-

 

If error, turbo prolog will return

to the ditor.

 

Then compile again till ‘No error’

SAMPLE TEST PROGRAM

Run      Compile      Edit     Options     Files   Setup    Quit
Editor Line1   Col1   Indent  Insert Work.pro /* SAMPLE TEST PROGRAM */ predicates      likes(symbol , symbol) clauses      likes(frank,sue).      likes(Harold,ruth).		----Dialog----- Goal :-
--------Message---------	--------Trace----------

F1:Help F3:Search F4:Subst F5:Copy F6:Move F7:del F8:ExtEdit F9:ExtCopy F10:End

Goal : likes(Harold,ruth)<-! (return key press )

Turbo Prolog will reply to you as

True

Goal :     ( wait for next goal )

Expressing Facts

(English to (Turbo)T. Prolog)

 

The right speaker is dead (English)

 

Is(right_speaker,dead). (T.prolog)

 

Fact                               Relation

 

has_a(bill, computer).    has_a

is_a(collie,dog).              is_a

likes(sue,chocolate).       Likes

 

 

Predicates (examples)

 

employee(bill)

eligible(mary)

marital_status(joyce,married)

 

For example, you can express the fact that mary is married and is eligible for employment as

 

eligible(mary) and marital-status(mary,married).

 

Facts expressed as prolog clauses

 

English: Bill is an employee.

Prolog: employee(Bill).

 

English: Bob is married to Mary.

Prolog: married_to(Bob,Mary).

 

English:The speaker is defective.

Prolog: defective_speaker.

 

English: Tom is a student.

Prolog: student(Tom).

Goal : symptom(cold,runny_nose) <-!

 

Response from prolog :

True

 

Goal : symptom(cold,headache) <-!

Response from prolog :

 

Using rules to solve the problems

 

Here another example to use

 

rules to solve the problems,

 

using hypothesis- concepts

 

 

Goal : hypothesis(patient,disease)

 

 

Prolog display as follows:-

 

Goal : hypothesis(patient,disease)

 

Patient=Charlie,disease=german_measles
