Re: Separate buisness and display logic question

If you have a situation where you cannot change the parms (perhaps
because the program is called in multiple places) but you need
additional data the LDA is a good tool to use. Another example is
setting up the environment so all of the programs in a job have access
to necessary data without the need to pass it around. Using the LDA
also has less of a performance hit than other solutions.

If you are concerend about standardization then you can create an LDA
standard for your shop, just like you do with other everything else.

Just because something is old doesn't mean it isn't useful. What are
your objections to using the LDA?

Jon's right on.  I haven't found a need for the LDA since ASNA's Call/Parm
was available on the S/36.

I find the LDA is a good place to put stuff that other programs might
need.

Aaaarrrrgggggghhhhhhh! Please tell me that was missing a smiley.

That what it's there for.

No it isn't Albert. It is there as a nasty reminder of the bad old days
when we couldn't even pass parms. Actually the days when one program
couldn't even call another directly without going via the command
language.

I just don't understand why anyone would use it today when there are so
many better and less error prone alternatives.
