Then what would the source type be?

Whatever the type of the module is. RPGLE, SQLRPGLE, CLLE, C, etc. 

Here is an example of a program that uses a CLLE, RPGLE, SQLRPGLE and C.
Not real but to show the concept. 

EX0001     - Top Level to bind it together into a program. 
EX0001_M01 - CLLE module. 
EX0001_M02 - RPGLE module.
EX0001_M03 - SQLRPGLE module.
EX0001_M04 - C Module. 

So the top level to bind it together is. 

CRTPGM PGM(YourLib/EX0001) 
  MODULE(EX0001_M01 EX0001_M02 EX0001_M03 EX0001_M04)   
  TEXT('Example create')          
  ACTGRP(QILE)                                      

A module is simply a way to group like code together. You can have any
number of modules that bind together to form or a program or service
program.

RPGLE, SQLRPGLE, C modules can have any number of procedures. CLLE
module can only have one. 

An example I use a lot is I have a standard error handler which has
three modules. 

XVERRH_M01  - Throw functions. RPGLE
XVERRH_M02  - Message storage functions. RPGLE 
XVERRH_M03  - Condition Handling functions. RPGLE

This all gets bound together to form Service program XVERRH.
