In fixed we work with external data structures to received information

and

pass information between programs.

*---------------------------------------------------------------------------------------------

D er6005ds e ds extname(er6005ds)

D wrtprba 4 dim(50) overlay(#tractprba)
Tp Reembolso Anteci.
D wrdesc 80 dim(50) overlay(#tracdesc)
Desc. Tp Reemb. Ant.

*---------------------------------------------------------------------------------------------

C *entry plist
C parm er6005ds

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???

Why do you not want to use this statement to get the data into the
original data structure that is declared with the arrays?

ER6005DS = P_ER6005DS;

Otherwise, since neither LIKE nor LIKEDS will copy the number of
dimensions in an array, you would be forced to replicate the data
structure definition in the called program in order to get the same
definition with dimensioned arrays as in the calling program.

Note that this is not a FIXED vs. FREE issue. You would have the
same problem either way.
