[SQUEEZE command info]
|The only problem might be a deleted file at

Dunno about RT11, but VMS also has the /ERASE
option on the DELETE comand, to write a pattern
over the old file. Somewhere I've seen another
version that had a parameter for the number of
times to overwrite the file...
Anyway, VMS help is online!
