Re: the ASSET issue again -- BPCS-L

All true, but this stuff wouldn't fly in a *nix shop.  Some where out
there some propellar head has written an AS/SET optimizer or beautifier
for AS/SET generated C code.  So why do 400 programmers sit down and
take it?  Sure it is a case tool, but if you know it will generated RPG,
write it so that it generates optimized RPG not garbage (and I do mean
garbage). 

It can be done, just take a look at the code generated by Macromedia's
Dreamweaver 2.0; compare that code to code generated by Frontpage 2000
and then by a competant HTML author.  You will see that Dreamweaver
generates some of the most elegant HTML on the planet (even better than
some hand coders).  Now HTML is a free form language, and a highly
complicated one at that, so if Macromedia can generate efficent and
pretty HTML why would you settle for ugly and inefficent code from your
ERP vendor?  And why would you deffend the tool maker for producing such
garbage??   Makes no sense to me.
