From Wikipedia, the free encyclopedia.
DOS/BATCH 11, as known simply as DOS-11, was released in 1970 and was the first operating system to run on the Digital PDP-11 minicomputer. DOS/BATCH 11 was not known to be easy to use even in its day and became much less used in 1973 with the release of the RT-11 operating system.
DOS/BATCH 11 came with XXDP, a diagnostics and monitor program for the PDP-11. Like other Digital operating systems, DOS/BATCH 11 also had a FORTRAN compiler.
