Graham,

I think your original idea of copying source and disabling fields with PR
and ND attributes is going to be the easiest and most reliable means to
accomplish your goals. A couple of gotchas to look out for..... Make sure
you don't reorder or remove any fields, including indicators (unless the
screens already used INDARA) as that will change your buffers and make the
screens incompatible with your applications. Compile the DSPFs with level
check *no (though I'm not sure if the format level ids will change if all
you do is change attributes). 

hth,
Eric DeLong

Subject: Altering field display attributes by user without touching DSPF
s ource


We're running a ERP package, BPCS as it happens, and the company is after
some form of field level security by user.

They're basically looking to protect or non-display specific fields.

We've identified 50 odd programs with affected display files.

We don't want to go and modify the program code.

We've considered  copying the dspf source and creating a set of Display
files in a separate library with the particular fields DDS attributes set to
PR/ND and loading this library higher in the library list than the std DSPF
based on user.

Is there any way of grabbing the buffer or bit stream sent to the display
(5250 emulation used in all cases I believe) and altering the attribute
settings at that point?  If so how and what skill set would we need to
acheive this?

Thanks in advance 




Regards

Graham Smith
