In the past I have use AMBLIST to show the structure of a load module. (
Or just rebind the load module)
This provides info on static code
My AMBLIST gives info like
RESIDENT CLASS: C_CODE
CLAS LOC ELEM LOC LENGTH TYPE
0 4610 ED PRINTMOD#C
B8 B8 LD print_ESD2
4D8 4D8 LD print_nam-_entry
690 690 LD fd_print_-lasses
980 980 LD print_ESD
9C0 9C0 LD print_cu_-_entry
B50 B50 LD print_cu_entry
D50 D50 LD fd_print_-_units
13C8 13C8 LD test_fdata_api
17F0 17F0 LD main
1A08 1A08 LD printHex
1F90 1F90 LD print_classes
22D0 22D0 LD print_com-_units
Another program copies in an RACF stub.
The output has
IRRSDL00(LD)
CLASS: B_TEXT TEXT TYPE: UNSPEC
NAME SPACE: 1 SCOPE: MODULE
ATTRIBUTES: GENERATED,STRONG
so we can see that this is an assembler code ( B_TEXT)
See MVS Program Management: User's Guide and Reference SA23-1393-60
There is a binder API in SA23-1392
Dynamic is much harder. You can have calls like DLLLOAD and you give a
string.
I don't know of a way of finding these.
You might be able to get who is using it from DB2 audit information
