Re: Looking into the Program stack

["David Morris" <dmorris@xxxxxxxxxxxxx>]

István,

Fear not, (at least on this one). A few modules, service programs and a single 
display file 
containing about 3000 lines of code should be able to completely replace your 
100 programs.  
You can download an example of this code from Midrange Computing at:

http://www.midrangecomputing.com/ftp/prog/99/991205.zip 

This program will use more system resources than a single RPGIII lookup, but it 
will save you 
hundreds of hours in development, compiling, testing, etc.  That is a fair 
tradeoff.

...What fears? I give you one as an example: in RPG-III, it is common to use
F4 to call a list (a subfile program) behind a code to make selections or
give further information. We have in this package about - let's say - 100
of such little (1.500 lines) programs. Do I make them all become one big
serviceprogram, which contains 100 modules which make in sum 150.000 lines
(just a lot of zeros, someone may say??); each of them has a DSPF of -let's
say- 1000 lines (another zeros, after a 1). Makes this sense? How does the
Main Storage act, loading the equivalent machine code of 250.000 lines,
when one finger presses the F4 Key? Is this not "baking a big pie",
resulting in bad performance, unnecesserily buying a bigger machine? Just
feeding Dollars into IBM? - Was the OPM construct not better from this
view: one fingertip on F4 loaded only the equivalent of 2500 lines? - Where
am I wrong?...

Thank you for your attention
