Now if you populate the rest of the elements you might be lucky and get a hit - but most likely not. If it was not found in 8 then say 12 would be checked.

If that is too high them next would be 10, and so on. IBM documentation is precise but unclear. For sequenced arrays, with ASCEND or DESCEND coded, the BIF does a binary search and the end result may be different from the one returned by the LOOKUP opcode.

Without the ASCEND, I do not believe you can force the binary search assuming you don't use the C search routine , which is more work.

Binary searches are much faster than full table scans. You just have to know when using the binary search makes sense; if you do use it, you need to have the blank elements at the beginning if you are going to search for them rather than just knowing where they are, which I prefer..

Efficiency is never my first priority, but proper table handling can make a serious difference. Data base tables can be used instead of some not all arrays, but will generally give you a big hit in run time.

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!!!

Every College teaches the Evils of GOTO's. I guess some fell a sleep during that class You cannot fix IGNORANT developers.

Just force them to maintain their own code! It seems to work most times! When converting character data to numeric, be sure you understand the format your character data will be in, and use the appropriate test for that format.

TESTN tests whether a character field can be MOVEd to a numeric field properly, so it expects zoned-decimal format: all characters numeric, except the last character can also be x'C0'-x'C9' for positive numbers or x'D0'-x'D9 for negative numbers.

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.

If OP really needs 'validate-only' then this is not a good answer.
Rpg Bif 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. 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. 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. 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. RPG Built In Functions. From MidrangeWiki.
