Hi,

   Is it not possible for you to do a CALL to QCMDEXC from your Cobol program so you can use the RTVDTAARA command. You just have to declare 2 variables : The first one should contain the command to be processed by the QCMDEXC program. The second variable should be define as a 15,5 packed digits. This variable should contain the real lenght of the command that you give to QCMDEXC.

Hope this help.

Bye

I think you will need to create a CL program in which you embed your RTVDTAARA command, and then call that CL program from your COBOL program.  Here's a very simple sample program:

PGM PARM(&DATAVALUE)
DCL VAR(&DATAVALUE) TYPE(*CHAR) LEN(10)
RTVDTAARA DTAARA(MYDATAAREA) VAR(&DATAVALUE)
END

and then in your COBOL program:

01  DATAVALUE PIC X(10).
CALL "CLPROGRAM" USING DATAVALUE.

I'm not 100% confident on the syntax above, but I think you can get the idea of what is needed.

As far as I know, You can read and write data to an DATA-AREA exactly the same way as you do this for your LOCAL-DATA-AREA (with DISPLAY and ACCEPT).
This is only functioning when the data area is already opened in a previous step.
(So actually it is more like reading a 1 record file.)
