Re[4]: Fw: File in CL Program -- RPG400-L

     That's true. I did forget to state that - I just kind of implied it by 
     the 'IBM supplied' statement. I had put these cmds on my 'things to 
     take with me if i move to another shop' list - thus being sure to keep 
     the code.  Then, I would have to check to be sure that no one else had 
     a cmd by the same name that did something else...and so it continues.  
     I have to keep in mind that there are some on the list that are new to 
     this and be sure to not to inadvertently confuse them.
     
     Thanks, Peter, for reminding me what happens when I assume. <bg>

Hi Jodi,
     
You are correct except that RCVF is available on *all* AS/400's, whereas the 
READ, UPDATE, WRITE commands are only available where someone has installed 
them. As a programmer going in cold to an AS/400 shop, I know RCVF will be 
there, but even if READ, UPDATE and WRITE are there, how do I know they are 
the same as the homegrown READ, UPDATE and WRITE I used at the last shop I 
was in?
