RPG IV - Built-in Functions through IBM i v The original release of RPG IV included a set of built-in functions. These built-in functions were: %ADDR, %PADDR, %SIZE, %ELEM, %SUBST, %TRIM, %TRIML, %TRIMR. In addition, under OS/ V3R2 and V3R7 the %PARMS built-in function was introduced. Since then, several built-in functions have been.

Question feed. RPG Built-In Functions %BIF When IBM introduced RPG IV (RPGLE) back in the mid 90’s, most of the RPG III opcodes were converted into built in functions. This makes for more readable code and efficient programming. The built in functions each do a particular function just like any opcode would have done. RPGLE Built-in Function List of Built-In Functions %ABS %CHAR %CHECK %CHECKR %DATE %DAYS %DEC %DECH %DIFF %EDITC %EDITW %ELEM %EOF %EQUAL %ERROR %FIELDS %FOUND %HOURS %INTH %MINUTES %MONTHS %MSSECONDS %OPEN %PARMS %REPLACE %SCAN %SECONDS %SIZE %STATUS %SUBST %TIMESTAMP %TRIM %TRIML %TRIMR %YEARS; RPGLE concepts Service prog. & Binding. From recent questions on Internet lists, and from one-on-one discussions with RPG programmers, it seems that many are confused about the usage and operation of a number of built-in functions (BIFs). In particular the BIFs %XLATE, %REPLACE, %SCAN, and %CHECK seem to cause a lot of confusion. In this tip, I focus on %CHECK and %SCAN. ILE RPG Built-in-functions %ABS - Absolute Value of Expression %ADDR - Get Address of Variable %ALLOC - Allocate Storage %CHAR - Convert to Character Data %CHECK - Check Characters %CHECKR - Check Reverse %DATE - Convert to Date %DAYS - Number of Days %DEC - Convert to Packed Decimal Format %DECH - Convert to Packed Decimal Format with Half Adjust. When %LOOKUP *NE LOOKUP I am sure most of us RPG developers have thought when a Built In Function, BIF, is introduced to replace an Operation code it would work the same way. Earlier this week I encountered a situation where it did not, where the %LOOKUP BIF can give different results to using the LOOKUP operation code.

But it would appear that that thought was forgotten somewhere along the way. That would not be very difficult to implement.

The MOVEx opcodes were excluded simply because they have goofy semantics. A lot of the old RPG opcodes sort of make sense but only if you understand the old instruction set.

Yeah, Hans - Barbara mentioned something about how the compiler reads things that makes some things unusable, I'll say - I forget the details, not important now, I suppose.

Something about the order of the keywords and all, and assumptions made around that.. Nice that they are gone, IMO. Vernon: First, there should be very little need for any of the opcodes excluded from free form calcs.

All old-style opcodes have alternatives. The next step in the evolution of RPG if there ever is to be one would be a fully free-form language, with all fixed form features fully deprecated.

They could start that process now with a compiler option, allowing statements starting in column 1, with no limit to line length. In fact, the free-form calcs were initially designed with that eventual possibility in mind.

I can understand the dislike of the need for the directives before free-form P, D, H, and F specs. But they're free form now, so the vast majority of new programs won't even need the directives.

Third, I know how the compiler works, I can't see any reason for not having a colon syntax for tags, like other programming languages. You read an identifier, which you do anyways for any statement, then read the colon.

You define the identifier as a tag name and move on. I am now afraid spaghetti logic will prevail and ultimately kill RPG, with usage of not only MOVE, MOVEL etc but also GOTO.

On the other hand it has hastened my desire to shift to Java as I am now sure of RPGs demise before my retirement :.

Hassan, I can't disagree with you more. I don't know how having the eyesores helps prevent spaghetti code. Personally, I want the code to flow, to be clean - and I will not often mix free-form and mixed-form - but I will when it helps me.

I might put it into a subprocedure, however, to keep the flow smooth in the main processing area. I in NO way am saying we should use GOTO and TAG and all that.

Please do NOT even begin to think that. I do say that IF I do need a fixed-form statement, I can do it without the extra directives, which provide no help at all in reading the code, they only distract me.

If someone wants to write spaghetti code, they will - no matter what the language encourages. If you want to write nicely structured code in RPGLE, you can, just as you always have been able to.

I agree generally with Hans that there are free-form alternatives for the fixed-form opcodes that were excluded.

I will admit that at a previous, in old code, with rather "interesting" uses of MOVE and MOVEL, I was reluctant to change that to free-form - that was more a matter of the time it takes, and often there just wasn't time to be sure the result was the same.

Quality assurance matters, right? So Hassan, there is nothing in the new free-form that will encourage less-than-desirable programming practices.

Tell you what, get the PTFs when they are available - maybe by the 15th - try the thing out - if you want to keep using the directives, you can - just as you could put SR at the beginning of a BEGSR spec if you want, it is just ignored.

Vernon: Then you're missing the whole point of free-form calcs. And I'm rather surprised I need to make this point at all.

The reason people use free-form calcs is so they can indent statements to properly show the structure of the code.

The advantage to indentation are so stunningly obvious that every programmer in every other language does it.

However, if you mix free-form and fixed-form calcs, you lose that. It's not a matter of spaghetti code.

It's a matter of clarity. This was exactly why we wanted a speed bump a dozen years ago, to make it more difficult to mix fixed and free calcs.

By the way, I'm not advocating for the addition of the GOTO opcode to free-form calcs. However, with SQL's WHENEVER, there does seem to be a need for a tag in free-form calcs.

The one does not necessarily require the other. On the other hand, it's hard to argue against GOTO in a language that also has pointers, in my opinion.

I consider pointers the "goto" of data structures. But that's another argument. Slackers and Amateurs use GOTOs One "Brilliant Developer" say that is what a subroutine does.

In the underlining machine code, it uses a GOTO. And he was doing "Advance Coding" just like MI Machine-Instruction.

See how "BRILLIANT" he is!!! The login page will open in a new tab. After logging in you can close it and return to this page. Share 0. Tweet 0.

Return the current date if no parameter specified. If the search value is not found in the lookup array, 0 is returned. In such cases you can simply remove the "Ascend" keyword and you will get the same results as with LOOKUP.

Another reason for doing this is that if there are duplicates in the array as you effectively have with blanks in this example even if you sort the array after adding a new value you will not necessarily get the same result.

I actually haven't tried this can't VPN into my system at my current location but I'm pretty darn certain your X'FF' solution will not always work.

When a binary search is executed you cannot guarantee which of a series of duplicates will be returned - you lucked out and got the first one, but normally you have to walk backwards through the array from the returned index to determine the first one.

I admit the example I gave in this post was very simple. I discovered this in a program I wrote where I had FETCH-ed 3, records from a file into a data structure array.

I was loading a subfile from the array. What I found became the basis for this post. These operate differently if the sort option is selected in the D spec.

Simple solution is to go out of free, use the C spec op code Lookup, and go back into free. This is if you have to maintain an existing program.

V7 can allow the sort based on a field in a DS. You may want to consider embedded SQL using cursors if you have the data in a database over a SQL view if it can be created.

I know this is a bit late, but I've had to deal with this recently and I tracked down an example of what I did back in This removed the problem with sorting an array with a bunch of blanks, as well as the binary search tracking through all those blank array elements.

This also means that, I cannot blindly convert any Fixed Format to Free format code, right? Yes, it does mean you should test.

But this should not be used as an excuse not to more to free format. It also means BIFs are not going to behave exactly like op codes.

I learned my lesson the hard way :. If the array gets that 'big', I'll use a work table instead. Chris Ringer. Es ist gut zu wissen, dass es hier unterschiedlich läuft.

So etwas sollte schon in der IBM Hilfe dokumentiert sein. It's good to know that it works differently here. Something like this should already be documented in the IBM Help.

The solution is to count the number of entries you enter as you pop them in. Then you only search the portion of the array that is used. I think you could have issues with LOOKUP with an array that isn't really sorted when it says it is as well.

That's why in the old days, we'd load the end of the array forward or initialize it to high values.

If it fails to find a match, it returns zero. It determines the point at which the comparison is to begin. This parameter is most commonly used when calling the BIF in a loop, where you need to skip past any instances of the search string that have already been handled.

BIFs are a vastly underutilized resource in RPG programming. Hopefully this series will help you gain a greater understanding of their utility and help clear up some common misunderstandings.
