DOS-11 included: • DOS-Monitor • Edit-11 (
text editor) •
FORTRAN IV (programming language) • Libr-11 (librarian) • Link-11 (
linker) • ODT-11R (
debugging program) •
PAL-11R (
assembler) •
PIP (file utility package) DOS-11 came with
XXDP, a diagnostics and monitor program for the PDP-11. Like other Digital operating systems, DOS-11 also had a FORTRAN-IV (Ansi-66)
compiler. FORTRAN-IV was not supported on PDP-11 systems with less than 12K of memory. DOS-11 systems running in 8K and 12K configurations ran a limited version of the
MACRO-11 Assembler (
PAL-11R in overlaid form). The DOS-11
operating system kernel was one file called MONLIB.LCL. The LCL extension was the acronym for LInked Core Image Library (or LICIL). An LICIL could be stored on any type of media that the DOS-11
operating system was distributed on (disk,
DECtape,
punched tape or
magnetic tape). When the LICIL file was installed (Hooked) onto a disk drive as a contiguous file, the monitor library name is changed to MONLIBCIL which could then be booted. The CIL extension was the acronym for Core Image Library. Core, was the term for the
core memory systems common to the PDP-11. A Core Image Library could be created with the CILUS (Core Image Library Update and Save) program. A MONLIBCIL typically contained the
resident monitor (RMON), the keyboard command routine, device drivers, EMT routines, the clock routines and the transient monitor. ==Legacy==
