Mainframe, MVS and zOS Discussion

Hi,

I have observed that when I am using "EXECIO * DISKW DDNAME", REXX will continue pulling input from the stack and from terminal input until it gets a null line. So a users will have to hit enter once to generate a null line. Why does EXECIO require 'Enter' more than once? Can there be better way of doing it? As of now I use the following two methods to overcome this:

1. Used the Queued() built in function instead of '*'.
2. Queued a null line before writing data from the stack.

It needs an EOF. But why use EXECIO, which is more designed for dataset access, when you can use PULL?
