 User defined command
AS/400, DSPDTAARA
Hi, I want to create a command such that the user only needs to specify (say) a data area name and the command should be automatically fired and perform DSPDTAARA on the parameter specified. I'm not sure how and where to start this because I don't want the syntax to be - mycmd (data area name). I want it to be only - (data area name) after which if the user presses enter, DSPDTAARA is performed. Is this possible?

Is this just for learning? Why create a new command when DSPDTAARA already does the same thing? See the Defining and documenting commands topic in the Information Center. — Tom

BTW, if you only have one data area, you can create a command with the same name as the data area. If you ever need to display a second or third data area, you’ll need a different command for each one. — Tom

The only way I can think of achieving a “simple to enter” utility for the user is to create a screen with an input field in which the dtaara name is entered and then the controlling pgm (RPGLE or CLLE etc) call the dspdtaara and outputs the resultant content to the screen.Otherwise ‘DSPDTAARA NAME’ is the only way to go.

The OP has a very specific format in mind. It can be done with just a CMD source statement plus two trivial PARM statements. It’s not even necessary to create a CPP. No separate display file either.
 
But command creation is a big topic. By knowing where the topic documentation is found and getting some background from it, the reason the simplest method works at all should become much clearer.
