ibm midrange - How to clear the screen on an AS400? -


Is there any way to clean the screen in the RPG for AS 400? I clrscr () c.

Looking for something with the same result

You clear the screen with the RPG , But it is not like clrsrc ()

The RPG does not directly address the screen. You work with a device file aka display file (DSPF). The standard way to create that file is with DDS source and DDS compiler (always available on AS / 400). DSPF has one or more records. The RPG program writes or reads these records. If you write a record defined with the keyword CRLR (), then your screen will be clear. Also read about the overlay () which goes hand in hand with this keyword.

All information is described in DDS

I think that you need to start with understanding the system. (It is quite simple but requires a little reading.)

Disclaimer: There are more ways to do this (including dirty and dirty tricks). But RPG + DDS is the preferred, standard and most used way in the world of iSeries.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
