Passwords and retention periods

When a file is generated or edited using the command CREATE-FILE or MODIFY-FILE-ATTRIBUTES then it is possible to assign a password for each access mode (READ, WRITE, EXEC) (Operand PROTECTION=*PAR(<accessmode> PASSWORD=...)).

READ-PASSWORD=	specified for read access(*NONE: no password necessary)
WRITE-PASSWORD=	specified for write access(*NONE: no password necessary)
EXEC-PASSWORD=	specified for execute access(*NONE: no password necessary)

When file attributes are modified using the MODIFY-FILE-ATTRIBUTES command, the previously specified passwords must be entered in accordance with the applicable password hierarchy (WRITE-PASSWORD – READ-PASSWORD – EXEC-PASSWORD).

When a file is edited (commands ADD-FILE-LINK-EXPIRATION-DATE=... or MODIFY-FILE-ATTRIBUTES...,PROTECTION=*PARAMETERS(EXPIRATION-DATE=...), it is possible to assign or modify a retention period.

Until this period has expired, any write access (by means of the “w” attribute in the file’s Basic Action Control List or because of an ACCESS= *WRITE in the case of standard access control) is ineffective. The file is therefore only available for read access.

When a file protected by a read and/or execute password is converted, the file loses the protection by the read and/or execute password in the process.
