Re: Specifying Check for Range in ILE RPG ?

Maibe this is what you are looking for?...

Position 28 (Limits Processing)

Entry Explanation

L    Sequential-within-limits processing by a record-address file Blank
Sequential or random processing Use position 28 to indicate whether the
file is processed by a record-address file that contains limits records.
A record-address file used for limits processing contains records that
consist of upper and lower limits. Each record contains a set of limits
that consists of the lowest record key and the highest record key from
the segment of the file to be processed. Limits processing can be used
for keyed files specified as primary, secondary, or full procedural files.
The L entry in position 28 is valid only if the file is processed by a
record-address file containing limits records. Random and sequential
processing of files is implied by a combination of positions 18 and 34
of the file description specifications, and
by the calculation operation specified.
The operation codes "SETLL (Set Lower Limit)" on page 697 and "SETGT
(Set Greater Than)" on page 693 can be used to position a file; however,
the use of these operation codes does not require an L in this position.
For more information on limits processing, refer to the ILE RPG
Programmer's Guide.

If you're using embedded SQL, yes. If you're doing traditional file I/O, you'll need do a SETLL and then check to make sure you're within the range after each read.

Subject: Specifying Check for Range in ILE RPG ?


Hi Folks,

Tried finding this in the online manuals with no luck. I could have
overlooked it since I am not positive what it would be called (didn't see it
in the Op Codes section of ILE RPG for AS/400 Reference). I need to check
for records matching a range in an RPG program. I have done this in a CL and
also with OPNQRYF but in this case would rather do it in an RPG program.

I am loading a work file with information to create "Bin Labels". A user
requests Bin Labels in a range of Row/Bin/Shelf. Each of these 3 fields is
3A. They will specify a starting and ending number.

For example they request labels for B2E 1A2 F99 to B2E 5B6 F99.

How do I handle this in ILE RPG, i.e. is there a %RANGE expression ?

Thanks in advance !

Chuck
