Use pointers & based variables.

Yes,   (Above MI) It's "object orientated",  so you ask for things by their
proper name(Lib, Name, Type)  instead of asking for things by their 
"Offset" address.  

And No.   (Below MI)  OS/400 of course uses pointers "alot".   Like "Space 
Pointers",
"Address/System Pointers", etc.

And in our applications.  Try passing a 50 byte parm to a program, 
and in the called program declare and use it as a 500 byte parm.

As one of the developers of OS/400(ie CPF) sayed;
"You will have a learning experience".

P.S
  PC based file system?  You do!   Get on a command line and type
the PC command "MD" for "Make Directory"  like   "MD BOOTH"
unfortunetly the OS/400(and CPF) had a DSPDIR command already for years
so they couldn't use that command,  so now key in;
"WRKLNK BOOTH"  This will display the "PC" Directory you just created.
Go to your real PC and if you're running the "Enhanced Client" you will
see the directory you just created within the drive letter for the 
AS/400 (like I:  or E:)

We now have IFS.
