Re: external data structure in free rpgle cant be use in DCL-PI ?

Surely the whole point of changing is to get to use better methods. And the
methods available in free-form are much better and more flexible. So why
penalize yourself - it makes no sense.

*the reason for changing is: *
*theres no more updates for FIXED format and in a few years it will stop
working on 5250*

the reason that in this initial phase we are trying to keep the and logic
of free programs as identical as possible, is in the sense of facilitating
those who nowadays provide assistance to customers during the night and who
are mostly banking institutions and not can be stopped for a long time be
familiar with the code and quickly identify what is happening

So why penalize yourself - it makes no sense*.-*
*I totally agree. And in aspects I've already managed to improve. At this
moment I already reduce many lines of code using \copy.*

Why? In fact if you;'re going to just do the same old same old why bother
to change to free?

Im starting to program in FREE and im creating an example of what the
structure of a FREE program should be, and must be identical as what has
been done for over 30 years by the company in fixed. and one of my
problems
is this one! My problem is not the arrays. I just want do now if its
possible to have the same parm entry in free like we have in fixed.

Entry
Parm. er5005ds

And ew use in program the fields name from that ds #xxxxrcode

And now
DCL-PI;
P_waapids like(ER5005DS);
END-PI;

Ok i have the same fields name like ER5005DS.
But in have to use p_waapids.#xxxxrcode = 2.

But we just want to use #xxxxrcode = 2 and only possible if in the
$pcpgm routine i have
Er5005ds = p_waapids

Do u understand ? In the past few weeks i've been using google looking
for
an answer. I've been reading everything about external data structure in
free. Im starting to think that Is not allowed like MOVEA does not exist
for FREE

Do u have like this

DCL-PI;
IM02_Inventory_V06 likeds(IM02V06);

?????


No, not like that. Here are a few other examples. After that is
a prototype used by calling programs. After that is the procedure
interface used by the called program. Also, notice that when I pass an
array definition, using LIKE, then I also have to add DIM to get the
number of dimensions -- since LIKE doesn't copy the number of
dimensions.


dcl-ds IM02_View1 extname('IM02V01') qualified inz end-ds;
dcl-ds IM02_View2 extname('IM02V02') qualified inz end-ds;
dcl-ds ImIm02_View3 extname('IM02V03') qualified end-ds;
dcl-ds IMIM02_InventoryManagement_V02 extname('IMITEMSV02')
qualified template inz end-ds;

dcl-pr ImIm02_GetTableData like(boolean_t);
pCaller like(PROC_PGM) const;
pTblData likeds(IM02_View1) options(*nopass:*varsize);
pIndArry like(IM02_Ary)
dim(IM02_VCol1) options(*nopass:*varsize);
pBefData likeds(IM02_View1) options(*nopass:*omit:*varsize);
pBefArry like(IM02_Ary)
dim(IM02_VCol1) options(*nopass:*omit:*varsize);
pCount like(bigint_t) options(*nopass:*omit);
pLibrary like(SRC_LIB) const options(*nopass:*omit);
pBefore like(boolean_t) const options(*nopass);
end-pr;

dcl-proc ImIm02_GetTableData export;
dcl-pi *n like(boolean_t);
pCaller like(PROC_PGM) const;
pTblData likeds(IM02_View1) options(*nopass:*varsize);

Because i cannot have the same name i declare on program interface.

I have to use a p_ IM02V06 Thats where the api receive the information
from
caller and because of that i have to do on pcpgm

IM02_Inventory_06 = P_ IM02_Inventory_V06.

In fixed u just put

C *entry
C. parm IM02V06.

Do you use that ext data structure on FREE declare on Program Interface
(DCL-PI) ?

I tried what you said and i cannot declare the external DS on \copy
with
qualified.


The following is copied from one of our production uses of an
externally-defined data structure. This is in a copybook and we use
/include to insert this copybook into the programs that need it.


Dcl-ds IM02_Inventory_V06
extname('IM02V06') qualified inz end-ds;
