Subj: REPLY TO MSG #5925 (UNDELETE -- COLD START RECOVERY)
It appears that your message got truncated. :( My idea was to have a backup file directory to attempt to get more robustness while I practice ML programming. I understand that the backup directory wouldn't be immune from programming error. :) Cold start erases the file directory, and it may be that there was no problem with the file directory, or many of the files. My idea was to provide some chance of recoverying these non-text files [assuming they haven't gotten munged]. Since most of the memory doesn't get cleared during a cold boot, one could store the backup file directory contained within the address space of the first BASIC program, which would be a parameter depending upon memory size; I believe a simple PEEK would be all that would be needed to determine where this space begins. :) Your idea of storing the backup directory elsewhere may help keep it safe--I dunno. Certainly your ideas on validation after or during the recovery process are EXCELLENT, as is your idea for only saving the needed bytes for recovery. :)
