There usually is an operating system call that you feed a "symbol" to that gives you a memory address.
This address could be:
(a) the start address of executable code.
(b) the start address of read only, or read/write storage for a data element of some sort.
This is kinda of exposed in the VM api via
VM->ioLoadModuleOfLength = ioLoadModuleOfLength;
VM->ioLoadSymbolOfLengthFromModule = ioLoadSymbolOfLengthFromModule;
