28 - turn security lock on or off.

Usage:

mme    gefsye
zero   CC,ARGLIST
zero   28,BUFFER

Where:

CC: is either zero or a courtesy call address.
ARGLIST: points to a list of arguments for this call. The format of this list is described below.
BUFFER: points to a buffer that can be used in this operation. This buffer should be 355 words long.

Description:

This version of MME GEFSYE turns the security lock on or off on a catalog or file. The argument list indicated by ARGLIST has the form

zero    RETURN_WORD,USERID
zero    CAT_FILE,SUBFUNC
zero    OPTION,0

where

RETURN_WORD

points to two words where MME GEFSYE can return a status. MME GEFSYE will initialize these words to zeroes. When MME GEFSYE returns, the first word will contain

Bit 0      -- 1 to indicate completion
    1-11   -- octal error code, or 0 for success
    18-35  -- pointer to additional error info
              (if any)

See "expl mme gefsye" for a list of common error codes.

USERID

points to two words containing the userid under which the program is operating (in BCD characters).

CAT_FILE

indicates the catalog or file to be truncated. If SUBFUNC is 1, CAT_FILE will point to the PAT entry for a file. If SUBFUNC is 2, CAT_FILE will point to a single word containing a file code, in the format

bci     1,0000FC

If SUBFUNC is 0, CAT_FILE will point to a pathname given in four word chunks: the first two words of each chunk gives a component of a pathname (first chunk the userid, next chunk the name of the first catalog, and so on); the last two words of each chunk gives a password. Each component name and password is given as 1-12 BCD characters, left-justified and padded on the right with blanks. If a component has no password, the password part of the chunk is all blanks. After the last pathname chunk comes a word containing the value -1.

SUBFUNC

points to a word containing a subfunction code. If the code is 0, FILE will point to a full pathname. If the code is 1, FILE will point to a PAT entry. If the code is 2, FILE will point to a file code.

OPTION

has bit 0 on if the security lock is to be turned on, and off if it is to be turned off.
