UPDATE X01.01
=============

UPDATE IS AN RT-11 FILE UTILITY DESIGNED TO UPDATE A WORKING DISK FROM A
MASTER DISK. THE PROGRAM IS USED AS FOLLOWS:

R UPDATE

UPDATE THEN PRINTS ITS NAME, VERSION NUMBER, AND EDIT DATE AND PROMTS FOR
A CSI COMMAND OF THE FORM:

<UPDATE-DEVICE>:<FILESPEC>{<SWITCHES>}=<MASTER-DEVICE>:

<UPDATE-DEVICE> AND <MASTER-DEVICE> MUST BE FILE STRUCTURED

<FILESPEC> CAN BE ANY VALID RT-11 FILE SPECIFICATION
WILDCARDS (* AND %) ARE PREMITTED
DEFAULT FILE TYPE IS *

<SWITCHES> ARE OPTIONAL AND ARE DEFINED AS FOLLOWS:
/Q - QUERY EACH FILE COPY
/L - LOG EACH FILE COPY
/P - PREDELETE FILE ON OUTPUT DEVICE BEFORE COPY
/X - OVERRIDE FILE PROTECTION

UPDATE WILL THEN SEARCH THE DIRECTORY ON THE UPDATE DEVICE FOR FILES WHICH
MATCH THE FILESPEC. WHEN A MATCH IS FOUND UPDATE ATTEMPTS TO LOOKUP THE
FILE ON THE MASTER DEVICE. IF SUCCESSFUL UPDATE CHECKS THE CREATION DATE
OF THE MASTER FILE AGAINST THE CREATION DATE OF THE FILE TO BE UPDATED.
IF THE MASTER FILE HAS A LATER CREATION DATE THE COPY OPERATION PROCEDES
IN ACCORDANCE WITH THE SWITCH SETTINGS. WHEN ALL FILES HAVE BEEN CHECKED
UPDATE PROMTS FOR A NEW CSI COMMAND. FILE PROTECTION IS PROPAGATED (IF THE
INPUT FILE IS PROTECTED, THE OUTPUT FILE WILL BE PROTECTED).

NOTE: UPDATE ONLY UPDATES FILES ALREADY IN EXISTENCE
ON THE UPDATE DEVICE. IT DOES NOT COPY FILES FROM THE
MASTER THAT DO NOT EXIST ON THE UPDATE DEVICE. IF YOU
WISH TO ADD NEW FILES TO YOUR DISK USE THE "COPY"
COMMAND.
