Small C library for the PDP-10 architecture and TOPS-20 operating system. The bin directory contains scripts for simulating ar, as, ld, and ranlib by using ftp and telnet to call MAKLIB, MACRO, and LINK on a TOPS-20 machine. Host, user, password, and working directory should be entered into the params.exp file. The include directory has all public header files. The src directory contains the library implementation. The .c files are written to be compiled with the PDP-10 target for GCC which can be found on http://pdp10.nocrew.org/gcc/. The .s files are in TOPS-20 MACRO syntax. The pre-compiled .o and .a files are in LINK .REL format.
