RE: Disabling edit and copy of source program in production library

A source physical file and a data physical file can both be secured at 
different levels.  You can even secure programs to read, or execute, only. 
 Be aware of SQLRPGLE programs though.  An execution of one often updates 
the program because there's a little area that stores the last access path 
or some such thing used.  Causes those nice little messages "This program 
was changed outside of (your change management software here)".  If you 
make those read only I think they'll still run, but there may be a little 
informational message in the joblog and future executions won't run any 
faster than the first execution.
