Easy way to convert CSV file to DDS file

csv excel cpyfromimpf cpytostmf

I am sure we have all been given a Microsoft Excel spreadsheet and told to upload the data from it into IBM i files. The first thing I do with the Excel spreadsheet is to save is as a CSV file. CSV stands for comma-separated values, the data elements, or columns, can be of varying length and are separated with a comma. It could be described as an Excel file without all the special formatting. If you have a Windows PC and you right-click on a CSV file, select "Open with", and then "Notepad" the file will look like this:

First,Second,,"4,444",5.5
First field,Second field,Third field,4.4,"5,555,555"

In conversations with other IBM i folks I am finding that the "Send file to host" function of Client Access is being shut off on their IBM is as it is rightly regarded as a security risk. What can be used as an alternative?

IBM i strategy and roadmap

ibm i commitment road map strategy

Sometimes Googling uncovers things I missed when they were originally released. This is an example: the white paper An executive guide to IBM's strategy and roadmap for its intergraded operating environment for Powers Systems was published in May 2014. In this 16 page document IBM explains their commitment to the IBM i.

In the introduction Doug Balog, General manager IBM Power Systems, explains Big Blue's commitment:

I want to assure you that IBM is committed to the IBM i platform as a vital component of our Power Systems portfolio. IBM i is key to our broader strategy of investing in enterprise systems and storage.

CL program that submits itself to batch

sbmjob program that submits itself to batch

There are many times when I want/need to have an interactive program submit a job to batch, and the interactive program would be so small it seems a waste to have such a program. For example the interactive program presents the user with a confirmation screen and then submits a program to batch that does all the processing. Perhaps the solution would be to have both the interactive and batch commands in the same program and it somehow know when it is running interactively or in batch.

Fortunately the 'Retrieve Job Attributes', RTVJOBA, command allows to retrieve which environment (interactive or batch) the job is running in. Combine this with subroutines in CL, see Subroutine in CL, and I can create a program that can run different commands in both environments.

How to cope with missing parameters in CL

clp clle parm missing parameter

When programming in RPGLE it is possible not to pass all the parameters between programs or procedures, using *OMIT in the calling code and %PARMS in the called code. The same functionality is not available in CL.

I needed to make a modification to an existing CL program, which is called from many other programs. If it was called from one program I needed to pass a parameter to it, if it was called by the others I did not need to use the parameter as a default value is used. I needed to make this quickly, before today’s night run. It would take too long to:

W ramach mojego celu, aby wyświetlić wszystkie IBM i grupy użytkowników na świecie miałem przyjemność znaleźć strona Common Polska.

Ich miejsce jest common.org.pl

Dodałem link do strony IBM i user groups.

Nie ważne gdzie jesteś w świecie, sprawdź, czy jest grupa użytkowników w pobliżu. A jeśli wiesz, grupy, która nie znajduje się na liście Contact Form, na prawo, aby wysłać mi swoje dane.

Formatting the email body in SNDSMTPEMM

sndsmtpemm email body

In December, 2013, I wrote a post about using the SNDSMTPEMM command to send emails from the IBM i, Email IFS files. It has become the most popular post on this blog, and the one that has generated the most interest.

Two of the most commonly asked questions has been:

  1. Can I send an email with a message in the email’s body and without an attachment?
  2. Can I format the text in the email’s body so it is not just plain text?

Redbook: IBM I modernization

ibm i modernization

IBM has published a draft of a Redbook called Modernize IBM i Applications from the Database up to the User Interface and Everything in Between. It primarily focuses on modernizing the traditional "green screen" UI to web and mobile.

Modernization is a broad term when applied to applications. It is more than a single event. It is a sequence of actions. But even more, it is a process of rethinking how to approach the creation and maintenance of applications. There are tangible deliveries when it comes to modernization, the most notable being a modern user interface (UI), such as a web browser or being able to access applications from a mobile device. The UI, however, is only the beginning. There are many more aspects to modernization.

It includes chapters featuring the following programming languages:

  • RPG
  • EGL (does any one use EGL?)
  • PHP
  • Java
  • HTML, CSS, and JavaScript

You can download it, as a PDF, here.
