Dbase

*  HELLO1.PRG
*   Sample program that clears the screen,
*   and writes "Hello World" at the screen 
*   coordinates: row, column (10, 10).

row = 10
column = 10
clear
@ row, column SAY "Hello World!"


Another way is:

*  HELLO2.PRG
*   Sample program that clears the screen,
*   and writes "Hello World" on the screen.

TEXT

        Hello World!

ENDTEXT

* HELLO3.PRG
*  Sample program that keeps saying "Hello World!"
DO WHILE .T.
   ? "Hello World!"
ENDDO

I would like to add a listing of the infinitely looping "Hello, World!"
printing program for DBase 4, apparently missing from the list...
(Hey! You've got FORTRAN and Matlab, why not DBase 4 !)

Here it is:

SET ECHO OFF
CLEAR
DO WHILE 1=1
     @1,1 SAY "Hello, World!"
ENDDO
