Re: %Kds second argument

Hi Stuart

That is what I thought but wasn't sure how to explain it, that it had to be known at compile-time - perhaps the call the the database component needs to have that set at the time, so a variable is too late.

One way to do it, that maybe the OP mentioned, is to use a SELECT block - clumsy, I know.

I ran into a similar challenge when writing up handling date and time conversion in an OAR handler using, I think, the %char() function to get the expected format that was in use in RPG - the format has to be hard-coded - it can't be a variable. I did use the brute-force, SELECT-style approach - RRRRREALLY ugly in my estimation. Bruce Vining suggested using CVTD and CVTT MI functions, and that is a bit more complicated to set up but does let me use variables.

I guess I was really turned off by the relatively huge SELECT blocks!

Cheers
Vern

No, unfortunately there is not any way to specify a variable there. I've
always WANTED to do so, but the compiler has never allowed it. The
reference manual does not indicate this limitation, but the compiler
enforces it. The compiler gives this explanation of the error:

"The second parameter for %KDS must be a numeric value with zero decimal
positions known at compile-time. In addition, the value must not be greater
than the number of subfields in the data structure specified as the first
parameter for %KDS."

Hi all



I try ..

is there anyway to use the second argument (subfields number to use) as
variable ?

i.e. Reade %kds(Kds: nFld ) Myrec;

Thanks
