File permissions allow for shared read. The file is used in a non-buffered mode so data is written directly to the disk. Globals Multi-way Balanced Tree structure. Each global is stored separately and may contain optional pointer blocks if it is larger than 4K in size. Routines Routines are stored in 4k disk blocks and are loaded into memory upon demand.
All users share the same memory copy.
Directories Routine and Global Directories are stored as global structures subscripted by the namespace. A user definable path table can specify the search order for finding a routine. The system console emulates a VT220 and supports most standard ANSI escape sequences and function keys. The port number of telnet defaults to port 23 but can be changed in the M3.INI file. Version 2.0e defaults to port 123.
