Re: Like keyword not keeping format -- WDSCI-L

I have made substantial improvements to the zoned/packed/numeric typeness
with the 9.5.1.2 release in line with what Barbara mentioned are the
non-obvious rules of RPG.

In general, do a program verify to see what the compiler actually thinks,
if it disagrees with the outline view, please open a PMR.
So far I don't see where the outline view is getting it wrong in the cases
mentioned on the list.

Thanks,

Probably not - but you'll find it (and a bunch of other D-spec/dcl stuff)
in this piece:

It would be better if the DS in question did not actually define the

field's type but rather just named it. That way it always picks up the
fields definition from the file.

That looks like it. The prog that has it as zoned includes a /copy of a

DS in which OHINV is defined just like the file, zoned. So it changed from
the file definition version to packed, except that there is a DS that
reaffirms it being zoned so it does not change it to packed.

Verified by putting the DS in the program that changed it to packed, it

now does not change it to packed.

Agreed on the reliability of the outline.

Really surprised I have not encountered this problem before when

expecting parm data to maintain type using LIKE.

Thanks.

What started this was passing a parm between 2 programs. Both using the

same file and field as the base of the LIKE. Both programs used I619 Like
(OHINV) - one program would pass I619 as zoned and the other would read it
in as packed, so the call would crash because of it.

I think of the Outline View as a work in progress. If it seems
snookered, I revert to the compiler listing.

With respect to the mis-matched parameter definition, make sure OHINV
isn't in a data structure, because that will override the Db2

definition.
