Anyways just copy out all the SQLBOOKS* files and then from the binn directory grab the INFOVIEW program. To view the books just run “ INFOVIEW SQLBOOKS.MVB ” and you’ll be set! Some of the other older tools like Visual C++ 4.x also use this InfoViewer format, and you can copy all the other associated files, in the off chance you want to ... copyout (pde_t *pgdir, uint va, void *p, uint len) ...
