Re: Service Programs

[dmosley@xxxxxxxxxx]

I found this defintion on the web.
"When creating a service program, the system calculates a 'signature' for
your service program. This works in a similar manner to the way 'record
format level checks' work on a database file -- if something in the service
program changes, they prevent you from possibly accessing it incorrectly."

To be more specific, if something changes in any of the procedures
parameters, this would cause a Signature Violation.

So let me get this straight, with a service program, I can change the its
module and I do not have to recompile the program? And what do you mean by
"signature"?
