This is a VERY preliminary program, and definitely incomplete. ALTDRIVE allows dynamic reconfiguration of the DSKDRIVE rsx system (See the separate DSKDRV13.LBR release). With a copy of COOKBOOK on the default drive, execute: d>RUNPCD ALTDRIVE or d>RUNPCD ALTDRIVE (cookfile) to use other names than cookbook Everything needed to re-compile is available on several RCPM systems: NITEOWL (414) 563-9104 TORONTO (416) 231-1262 MET-CHEM (The most up-to-date versions) (203) 281-1438 (Met-Chem is a FIDO system) The version of RUNPCD included in this library has been patched to allow the "syscall" function to return a 16 bit value, which is needed to access the configuration tables. In all other respects it is the standard release. If PCDHELP.PCD is online then d>RUNPCD (with no parameters) will give help. C.B. Falconer 85/5/15
