Re: Pointers? Based variables? in CL?

95% of what most people on the iSeries are concerned with are the 
'traditional' stuff like file i/o, etc.  And you can already do most of 
this with CL.  Granted, api's and pointers do open up a whole lot of 
possibilities, but if people can already write a CL program that will read 
the employee master file and manipulate it, then, again, the 95% has been 
reached.

You need to do other security methods to control your data.

If it's such a big concern - delete or rename the commands CRTCLPGM & 
CRTCLMOD.  That should give you a nice false sense of security.

hi Vern,

bothers 
> you if it "comes true"? I mean, the stuff is here now.

I think he's referring to the ability to call APIs that return pointers, 
such as string manipulation APIs, record read/write APIs, IFS directory 
reading APIs, etc.

That stuff is currently only available through HLLs, which require the 
customer to buy a WDS license from IBM.  Tom's concern is that now systems 

where they deliberately didn't buy the HLL compilers (possibly to prevent 
people from doing development on the machine because of the potential 
security/stability risks of allowing development) will now have access to 
most or all of the HLL's capabilities through ILE CL.

The *BYVAL stuff that we got in V5R3 is also a big deal. When you combine 
the two (pointers and *BYVAL) this gives you access to pretty much every 
API on the system, and unlocks pretty much all of the functionality on the 

system to a CL program.

And, I think that's Tom's point :)
