Identify the application. The goal is to define the limits that
surround a medium sized system area with as few interfaces with other
systems as possibly. Not so big that it is unmanageble to convert
and test in one process but not so small that the advantage of
large scale operation is lost.
-
Identify the Critical Event Horizon and the exposure to your
buisiness in order to justify the needed resources. Also consider
the different options, mainly Replacement, Conversion or Continuing
(with possibly loss of century-spanning functionality).
-
If Conversion: Check the integrity. You might use my free
tool for checking source integrity.
You can copy all
source that should be converted into one library, and dependant
not-to-change
objects (including file data) and their source into another.
It should then be possibly to compile (with only the two
libraries in the librarylist) and run the applications
in that simple environment to test the reference integrity.
-
Agree with me that I can estimate the time
and payment needed for the conversion. If so, you can send me a tape
with the two libraries mentioned and expect an estimate back in
two or three weeks. I will charge a small amount for an estimate.
About USD 1.000 if the tape holds a complete base for the estimate.
The total cost can be expected to be between USD 0.02 and 0.20 per
RPG source line, closest to the low end for applications developed
for internal use. A fixed quotation is a possibility.
-
If we make an agreement I will timely return the converted
application in a roughly tested version. During the time I
use for conversion it is not necessary to stop
internal development of the application. Because most work
with my conversion tool is 'defining conversion reposatory'
it is no big deal to replace with changed source. It is
only needed to keep a log of changes done.
-
Both during the initial conversion period and when correcting
what might be found during the test, I suggest that a person from
you with the necessary commitment and
an e-mail address is pointed out to ease the process.
