We still use multiple source files. I guess that part of the reason is that 
we're
used to have it that way since the S/38 days, but some of us still use
the programmers menu (!). We have implemented an exit program to add extra
parameters to the CRT* commands - (like bndsrvpgm) stored in source comments in 
the beginning of each source. We could probably have used user defined options 
in
PDM in stead...

Another reason is that restore of members (if one should need it) takes a 
*long* time
when thousands of members are placed in the same source file.
