assembler maintains a table where Entry address for all lables being declared in the program. In below, symbol table will have details like "Para-1 000A", "VAR-1 ----" and so on. Address(entry point) for MVC instruction will not have its entry in symbol tabel as it does not have any label to be referred.. Still Location counter used to maintain address for each instruction. Here Location counter will have address of MVC as '000A' and its length of instruction. Here Para-1 address and MVC address is same as 0H does not reserve storage.

For example, Para-1 address is at X'000A'.

para-1 DS 0H
