Hi, You need to define your data area in your program and retrieve the data from it directly, you don't need to use the PLIST or PARM statements. Here's a link on how to define and use data areas in RPGLE. <a href="http://publib.boulder.ibm.com/infocenter/systems/scope/i5os/index.jsp?topic=/rzasd/sc092508962.htm&tocNode=int_232427">IN (Retrieve a data area)</a> Regards, Martin Gilbert. ---------------------------------- That's right Data Areas are accessible to all programs, therefore you don't have to pass them as a parameter. You just have to define in your Data Specification and access it with the operation code IN. Formerly the definition was done through an operation code <b>DEFINE</b> and <b>*DTAARA</b> keyword in factor one. <b><i>Example:</i></b> <pre>* The result field entry (TOTNET) is the name of the data area to * be used within the ILE RPG program. The factor 2 entry (TOTAL) * is the name of the data area as defined to the system. C C *DTAARA DEFINE TOTAL TOTNET</pre>

Hi,

Slight amendment to above statement :-

Data Areas are accessible to all programs

Should read

Data Areas in your library list are accessible to all programs

It sounds as if you want to use the contents of the data area when you call the program from the command line, and you don’t want to write a CL program, and you don’t want to declare the data area in your program.

Well, there are only two ways to do that. First is to look at the data area, see what the value is, and use that value in the parameter list.

Second is to change your mind and write a CL program or declare the data area in your program.

You CAN access a data area which is not in your library list, by using the RTVDTAARA CL command. You can only use this in a CL program.

Is there some specific reason why you don’t want to use a CL program or declare the data area in the RPG code? If so, please let us know. It won’t make any difference to the answers, though.

RPG has allowed reference to data areas through variable names since V5R3. The variable may have the name in the form ‘LIBRARY/DTAANAME’. That is, it does not have to be in your library list and you don’t need to use RTVDTAARA.
