You can determine at run-time the size of a variable.
By Bruce Vining
I recently conducted a workshop on best programming practices when working with system APIs. One of the practices I recommend is to avoid hard-coding values such as variable lengths (or anything else for that matter) throughout the program. Assume for instance that you're calling a retrieve type system API that has four parameters as shown here:
Have you tried using the C run-time date and time APIs?
By Bruce Vining
In the two most recent articles of this column (here and here), we have looked at the CEE date and time APIs and seen how easy it is, when working with Lilian seconds, to perform operations such as adding six hours to a time, comparing two time values, etc. without regard to the number of seconds in a minute, the number of minutes in an hour, and so on. This capability is not unique to the CEE APIs. It also exists with other APIs that are provided standard with your i operating system. Today, we will look at one such alternative set of APIs, the C language run-time functions--functions that you can also use from ILE CL. As a reminder, the task we are working on is to send an alert from one program (CHKLSTSND in the original article) when another program (SNDUPD) has not successfully run in over six hours.
Learn how to use the Convert Seconds to Character Timestamp (CEEDATM) and Convert Timestamp to Number of Seconds (CEESECS) APIs.
By Bruce Vining
In the last column of this series, we looked at the Get Current Local Time (CEELOCT) and Copy Numeric Value (LBCPYNV) APIs in order to simplify working with time durations involving seconds, minutes, or hours. Today, we will review the Convert Seconds to Character Timestamp (CEEDATM) and Convert Timestamp to Number of Seconds (CEESECS) APIs to see how these APIs can be used to provide a higher level of operational friendliness to the job at hand. As a reminder, the task we are working on is to send an alert from one program (CHKLSTSND) when another program (SNDUPD) has not successfully run in over six hours.
Date addition is nice, but what about hours?
By Bruce Vining
In response to the recent articles on working with date durations, I received a note from Lori N. asking if similar support exists for smaller time frames. Specifically, Lori says, "Thanks for the articles; they are very helpful. I have a monitoring job that checks a data area to make sure we have sent updates to another system within a specific time frame. I used CEEDATE to get today and yesterday, but I'd also like to use a time interval so I can say 'If we have not sent anything in the last 6 hours, send an alert.' Is there something that takes the current time and subtracts a specific interval so I can compare the last times? If not, I'll have to be satisfied with checking dates. Thank you for your help with this." To which I respond, "Be satisfied with checking dates rather than hours? We should never compromise on such a basic need when working on i!"

Control Language (CL) has seen many significant enhancements in recent releases. With V5R3, CL was enhanced with structured programming constructs such as DOFOR, DOUNTIL, and DOWHILE and the associated commands ITERATE and LEAVE; SELECT and the associated commands WHEN, OTHERWISE, and ENDSELECT; etc. V5R4 followed with additional enhancements, such as subroutines with the command CALLSUBR and the associated SUBR and ENDSUBR controls; data structures with the support of STG(*DEFINED) variables on the DCL; the ability to define compiler options in the CL source using DCLPRCOPT, etc. V6R1 continues this trend with several significant enhancements that impact the development and problem determination associated with CL applications.
Others will think you work for IBM.
By Ted Holt
A System i developer recently informed me that after several years of programming, he is finally learning to create commands. I am amazed that many developers have worked many years with the System i and its predecessors, yet have never created a command, but it seems to be very common.
This developer mentioned two areas that have given him trouble, and I was able to help him. First, he wanted to understand how to qualify an object. Second, he wanted to add help text to his command. I have seen this guy's code, and I know that he is very capable. I have no doubt that the commands he produces will be indistinguishable from those IBM ships with i5/OS. Here's the information I gave him. I hope it will be of benefit to many others.
Holidays should be fun! With CL-based variables, at least they're not a headache.
By Bruce Vining
In the last column in this series, we looked at how to calculate a date such that it would be a minimum of 60 days from an arbitrary date and ensure that the calculated date did not fall on a Saturday or Sunday. We accomplished this using the i5/OS APIs CEEDAYS, CEEDYWK, and CEEDATE. We noticed, however, that holidays were not being handled. When avoiding a Saturday or Sunday calculation, we would use the following Monday, which might be a holiday. In today's column, we'll look at one possible solution for bypassing holidays. Note that there are many, many possible ways to handle holidays. This is simply one: one that may be better or worse than other methods, depending on your situation.
Everybody loves Saturdays and Sundays, right? Well, no. Sometimes applications don't.
By Bruce Vining
In the first column in this series, we looked at the Get Current Local Time (CEELOCT) and Convert Lilian Date to Character Format (CEEDATE) APIs. Today, we will review the Convert Date to Lilian Format (CEEDAYS) and Calculate Day of Week from Lilian Date (CEEDYWK) APIs.

Let’s face facts: servers don’t hack other servers. Despite the avalanche of regulations, news headlines remain chock full of stories about data breaches, all initiated by insiders or intruders masquerading as insiders.
User profiles are often duplicated or restored and are rarely reviewed for the appropriateness of their current configuration. This increases the risk of the profile being able to access data without the intended authority or having privileges that should be reserved for administrators.
Watch security expert Robin Tatam as he discusses a new approach for onboarding new users on IBM i and best-practices techniques for managing and monitoring activities after they sign on.
While introducing Sequel Data Access, we’ll address common frustrations with Query/400, discuss major data access, distribution trends, and more advanced query tools. Plus, you’ll learn how a tool like Sequel lightens IT’s load by:
