The Cambridge (England) Phoenix system's BCPL implementation under MVT (OS/370)
had access to a loader so that one could load BCPL or FORTRAN modules, to allow
DIY overlaying in a restricted virtual address space (44K if memery serves me
aright). Since loading was from a disk dataset, one *could* I guess generate a
module and then overlay and execute it ... I dont know that anyone did thou.
