Description CLR$(666) clears with NUL (00 hex) the entire text string from the first word
designated by S until the NUL code (00 hex). The maximum number of char-
acters that can be cleared is 4,096. If there is no NUL before the 4,096 char-
acter, only 4,096 characters will be cleared.
Note CLR$(666) can be processed in the background. Refer to the SYSMAC CS/
CJ/NSJ Series PLC Programming Manual (W394) for details.
