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.

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.

If you have 16 elements then the first element checked will be 8 or 9 depending on the algorithm if the empty elements are space filled then the key being sought will be higher and eventually the 16th element will be found.
But if you were searching for the value you placed in element 1 you would never get a hit. 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.

So much so I wrote a post about it: MONITOR for errors in RPG. Before to know TESTN statement i put the field to test with MOVEA in an array with the numer of elements equal to the number of characters of the field to test, after i did a loop to control each element of the array with LOKUP statement on a table containing "".
If all the element of the array gave found on a table that means the fiels was numeric otherwise the field was to be elavued as alphanumeric.
Might be helpful to write follow up to this conversation with example of function to wrapper this logic for generic number checking with any length.
Very often, the test for 'is this a number' precedes converting that string to a numeric field. Many times, this is some sort of data import from an external source, say a CSV file.
In , Barbara Morris published a routine to extract the number from a string which allows one to specify a currency symbol, decimal and thousands separator symbols.
That brings up a good question. Does the FREE FORM monitor method for test numeric have any issues with negative numbers?
I would test this myself--but being unemployed I don't have a iseries in front of me. Can someone please test this? I have tested with the minus sign at the front, ' How about you read Simon's article before posting the same solutions he already provides?
So mixing in a TESTN will not be so ugly as it would have been before. Coming soon to a v7. I don't think it works like that. There is no TESTN statement in free format so you can't use it.
If that were the case there would be no need for the character and numeric bifs. Just continue to use MOVE and MOVEL. Sorry, Paul, I wasn't clear enough.
The compiler will ignore them. Free-form statements and fixed-form statements may be intermixed. Au contraire, mon frere!
Pardon my horrible French! I am of a different opinion - when non-free is needed, it will be much cleaner than it was.
For most of what we do, we will need only free form, of course. Barbara mentioned a specific item that requires fixed form - a TAG as the target for the WHENVER clause in SQL.
We can't even use a subroutine or subprocedure for that! And we can always make a subprocedure, to contain the majority of our fixed-form stuff, as needed.
This kind of test is a natural for that, eh? Holy Cow! Well, it looks like one step forward and one step back. If they really were concerned about TAG as target for SQL's WHENEVER clause, surely they could have come up with a better solution.
Many other languages use a colon to identify a label. There's no reason not to allow the same syntax in RPG. But why the concern now? Back when free-form calcs were designed, feedback from RPG programmers heavily influenced the design of the feature.
One concern from programmers that it should not be too easy to switch between fixed and free form calcs. Regarding TESTN to test if you have numeric data, please please please read the RPG Reference manual very carefully.
As Simon points out in his article, TESTN does not do what you want. You might be surprised that TESTN treats "M" as a valid numeric. Likewise, "" is not considered by TESTN as valid numeric.
Holy compiler directive, Batman!! As to getting something to really replace the opcodes that didn't make it, Barbara did lobby for some, like TAG, for the reason that there is no free-form way to specify the target of a WHENEVER.
But time and money and all that - you know the routine when doing development. The point of my last comments was to clear up something Paul Wren said - the question of using TESTN was not germaine - and the cautions are well-taken!
Vernon: Don't forget, I was there at the time. We knew about SQL's WHENEVER, but it wasn't considered a compelling enough reason to keep TAG.
If I recall correctly, I think the intention was to include a tag using a colon syntax at some point.As with all BIFs, one of the major advantages compared with the old op-code version is that the BIF can be used directly in a conditional expression—no need to create a temporary work variable and test that.
