Re: Absolutely neceesary DDS keywords

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Hello Bruce,

I have often found INDARA useful.  Because it causes a separate indicator area 
to be defined (with room for 
all 99) you can add new indicators to a display file without having to 
recompile all the programs that use it.

Now I realise that in most cases a single display file is used by a single 
program but when it is shared by 
many programs each using different formats INDARA saves some time because the 
LVLCHK doesn't change.

It also allows the display file to be used by any HLL without causing 
contortions for the programmer.  RPGers 
can ignore its existence and COBOLers will be grateful.

It costs nothing to use and is good practice -- although it is not absolutely 
necessary :).

Regards,
Simon Coulter.
