Program: NWCACHE is the disk cache included with Personal NetWare, Novell DOS 7, Caldera OpenDOS 7.01, DR-OpenDOS 7.02, DR-DOS 7.02, and Caldera Thin Clients/Lineo DR-DOS 7.03.
Note: This function is called by the NetWare Lite and Personal NetWare SERVER. It may also be called by future (post DR-DOS 7.03) COMMAND.COM before it returns to the prompt.
BUG: Some pre-BETA 17 (1993/09/28) versions of NWCACHE returned -1,0,1 instead of 1,2,3 for the memory type in CL.
