Re: Skip Records When Building a Subfile

That is because you are using "DO SflPag" to control the loop.
Since, sflPag is 12, it will only loop 12 times, which is fine until you
do a ITER to skip record. ITER is also being counted as one loop.

There are several ways to correct this problem. Base on existing code,
the easier (not the most readable) solution would be changing the "DO
SflPag" to "DOW Rrn1 - LstRr1 < sflPag"

Hi,
I am just getting started with subfiles, even though I have

been

programming for many years. (used Asset to create all display

programs). I

wrote a couple of simple maintenance programs successfully using Kevin

Vandever's book 'Subfiles in RPG IV'. I have a more complicated

subfile

to create, and I can't figure out how to do this using SETLL & READ.

If

all else fails, I will use SQL with WHERE statements. I do not want

to

display a list of all item classes, only those with a code in a

particular

field. When I do this, it leave a blank line on the screen where the
skipped record is. The first screen is fine (displays 12 records).

When I

roll, only 11 records are displayed (first skipped record). I

continue to

get missing lines until only half the screen is filled. Then, when I

page

down, it fills in the blank lines before going to the next screen. I

know

there must be a way to do this, but I have not been able to find it.

Here

is the subfile and the associated code. Any help will be appreciated.
