NOTA BENE:  if you just made "one line code change" to one procedure in one *MODULE in a service program, you could have used UPDSRVPGM to update the *SRVPGM with the new *MODULE and the signature of the *SRVPGM would have remained the same.

Hi everyone
We are on V7r3
We have a service program that has 6 procedures
Last Friday, I had to make  a change to one of the procedures - and that change was to insert one line of code into one procedure
Just to populate a field
Now - every program that uses those 6 procedures had a Program signature violation - MCH4431
As this is a relatively new service program - that number of programs involved is relatively small
So I just recompiled them - yes - I know I could have used UPDPGM
They are now working as expected
The binding program specifies a signature as well as the 6 procedures - in order
I am scratching my head as to why a signature violation happened
Any one any ideas as to what I can look at?
