CLUDMP is the compiler, and is a normal ITS executable. It has a variety of commands documented in CLU ORDER, but normally just the file name can be passed on the JCL. The compiler emits an intermediate CLUMAC file which is then assembled with MIDAS, leavning a BIN file. The BIN file is not a normal ITS binary, but has to be loaded into the CLU runtime. The CLUSYS directory has files needed to assemble CLUMAC files. ALPHA and OMEGA are inserted at the top and bottom, respectively. ALPHA in turn needs PASS1, TYPES, and COMMON. It is not known how LOAD is used, but it's also necessary in the compilation process. TS CLUSYS is the runtime system. The procedure "fload" accepts a string specifying a file to be loaded. It's an open question whether the two executables can be rebuilt from source code found on the scattered ITS backups.
