Fourth Generation Programming Language(General Purpose)

In the second nest, add the function of the paragraph to the number of pages: "<<", ">>" (black background). In this example, there are 24 items, 5 items per page, 5 pages. Every 2 pages for a paragraph. Screen description: ------------------------------------------------------- First Nest "Title" is Column 1 "Remark" is Column 2 First Page : Jump to the first page Last Page : Jump to the last page << : Jump to the previous paragraph >> : Jump to the next paragraph Pages : Selected Page is red. Unselected Page is black. ------------------------------------------------------- Second Nest "----Time" is Column 1 "ROCK N ROLL" is Column 2 FIRST : Jump to the first page LAST : Jump to the last page << (black background): Jump to the previous paragraph >> (black background): Jump to the next paragraph Pages : Selected Page is blue. Unselected Pa

Before you start, you need to know the meaning of several nouns Fourth Generation Programming Language(4GL), also known as Very High-Level Programming Language(VHLL). Domain-Specific Language(DSL) : Specific use, but it is difficult to have other uses. General-Purpose Language(GPL) : Not limited to use, Such as C, C ++, java, c # and so on.. But no one can say what programming language is 4GL. Maybe someone can say several nouns out and say: This is 4GL. It is wrong at this point. Because it must have the characteristics of GPL, which can be considered a real 4GL. So with the GPL characteristics of the 4GL is difficult. How hard it is ? If we started from Fortran in 1957, it has been 60 years old. Period after a number of high-end talent, but still fruitless. Time for a long time, it gradually thought that it was fantasy, and with the discrimination, just as 2GL against 3GL, history is repeating again. Before 4GL does not exist,and there is no entity, then we ca

Move to :  http://gp4gl.byethost7.com/Triangle_Star_Pattern.html "Triangle Star Pattern" often appears in the programming language practice. General-Purpose 3GL must be able to do it. Such as C, C++, Java, C #... Then the General-Purpose 4GL must be able to do so. If this programming language really has a General-Purpose attribute, it must also be able to execute and display its results. Triangle Star Pattern(C#) Edward 2016-09-27

DataGrid for 4GL with jumping As shown in the "Last Page" and "First Page". The first page and the last page are often used functions, I think the advantage is fast. The user does not need a page of a page to click back, so this control must also support. Generated Program Language : C# for Windows Form Edward 2017-10-09
