Tools for (the RMAC) Assembler

Most of the presented utilities are written in pure assembler — therefore relatively easy to understand — but many of the Digital Research applications are written in a high level language1 . However disassembled code of a high level language is much difficult to understand. In fact it concerns two utilities, the linker and the librarian. I used these programs because they allow faster library access using indexed .REL files (.IRL files). LINK.COM2 also allows the direct creation of RSX files

LINK : I did modify this utility slightly. Now the option [OX] does exist which creates an .RSX file the direct way. Therefore the option [OR] will not be used anymore. I also decided to disable the option [B]. The new option [V] logs activity on console. The option [S] now searches not only in an .REL library but also within an .IRL file.

LIB : I did implement some new options:

[E]:	Displays Public symbols as well as External symbols within a module
[U]:	List unsolved references in a library
[R]:	List label references in modules by a given search mask
[N]:	Console output with No pause
