GUARD Set Guard Protection for Files / Library Elements

SG Set Guards. Protect file/PLAM library element with Guards. If the name of the Guard profile (Read/Write/Exec Guard) has not been made known to CFS - either through an earlier GUARD command or Variable Action, or through an earlier SG/SGM Action Code - the names will be requested via a special mask the first time an SG Action Code is executed. For a description of this special mask, see the ONXGUARD Variable Action, page 5-.

SGM as for Action Code SG, except that the Guard mask will always appear.

SGN Set Guards None. The Guard protection will be removed for the specified data object. For files, this can also be achieved with the BS2000 command /MODIFY-FILE-ATTR file,PROTECTION(GUARD=*NONE).
