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

You should not be using LIKE. You should use LIKEDS.

That way all fields within the DS can be accessed directly try from the
parm. For example:

dcl-ds myParmDS Template; // Put this in a /Copy so all progs can use it
field1 char(5);
field2 packed(7:2);
field3 varchar(200);
end-ds;

dcl-ds parms LikeDS(myParmDS);

dcl-pr CallPgm ExtName('WHATEVER');
allParms LikeDS(myParmDS);
end-pr;

parms.field1 = 'ABCDE';

CallPgm( parms );


In the WHATEVER program.

/Copy the template(s)

dcl-pi .....
parmData LikeDS(myParmDS);
end-pi;

// example file use

CHAIN parmdata.field1 AnyFile;

If %Found(AnyFile);
parmdata.field2 = data from file
etc. etc.
End-If;


NOT TESTED - done in a hurry.

There are lots of examples on the web look for use of Qualified Data
Structures.

C *entry plist

And now we have to used FREE and maintain the same structure.
DCL-DS ER6005DS extname('ER6005DS') inz;
wrtprba char(4) dim(50) overlay(#tractprba);
wrdesc char(80) dim(50) overlay(#tracdesc);

but i can use the same ext DS in the procedure interface:
DCL-PI *N;
p_er6005ds like(ER6005DS);
END-PI;

The information from the caller is on P_ER6005DS.

And i have on the pcpgm always to do:

ER6005DS = P_ER6005DS;

e the ucpgm the inverse:

P_ER6005DS = ER6005DS;

Theres any way of receive the information not in P_ER6005DS, but in the

DS

declare with the arrays???
