Moving program objects from development system to working system

Hello everybody!
I have question abouth programs created with CRTPGM comand combined from 
more pgm modules or service programs. (programs are written in RPG and 
os400 version is v5.2 and PDA is V5.2)

If I create program pgmABC from program modules modA, modB and service 
program svpgmC on system1, what is necessary for system2 for programABC to 
works fine on it? Is it enough just to place pgmABC on system2 or there is 
something more to do?
I understand modularity on source level of one program but I don't 
understand does RPG program compiled from many modules acts as one during 
it's execution or it loads code of other modules and service programs from 
their specific fixed locations.
If I'm using Qxml4PR310 service program in qsys lib to create program 
xmlReader so do I have to have same service program on system2 that is 
used by end users.
(one more thing - what if I 'm using prototyped C functions, do I have to 
have same binding directory on system2??)

 

Thanks,
