    From Plt@VERT/MB to All on Sat Nov 10 23:06:57 2018
    I was looking at some code and I am trying to figure out what does the 770 mean on the following open statement?

    fopen var_001 770 "%/ntelval.tmp

    What does 770 do?

    Thanks

    unbaja creates random designations for stuff that is lost when it decompiles. atleast i think that's why.

    so if i had a variable that was named BUTT, when decompiled it would give
    it another designation

    Probably more to do with the mode the file is created with. 770 = rwx to
    both owner and group and no permissions to other.

    well it's an undocumented feature then.

    *FOPEN <int_var> <#> <"str" or str_var> FILE_IO.INC
    args: handle access path_and_filename *------------------------------------------
    This function opens or creates a disk file (path_and_filename) for read and/or write access. This function is the Baja equivalent of the standard C fopen() function. No file I/O operations can be performed on a file until it has been opened with this function. The 'handle' argument must be a defined integer variable name. The 'access' argument is the requested open access. The access flags (defined in FILE_IO.INC) are:

    Access Flag Description
    ~~~~~~~~~~~ ~~~~~~~~~~~
    O_RDONLY Read Only
    O_WRONLY Write Only
    O_RDWR Read and write
    O_CREAT Create (create if doesn't exist)
    O_APPEND Append (writes to end of file)
    O_TRUNC Truncate (truncates file to 0 bytes automatically)
    O_EXCL Exclusive (only open/create if file doesn't exist)
    O_DENYNONE Deny None (shareable, for use with record locking)

    I was guessing, it looked like a file mode. I never claimed to be an expert.

    i'm not seeing any 770
    so you are saying exclusive+truncation+create = 700 ?
    i didnt know it could be used that way

    You just add or bit-wise-or the value together.

    so you are saying exclusive+truncation+create = 700 ?

    Right.

    i didnt know it could be used that way

    Same as *nix permissions/mask values.

    If I'm not mistakened, the 770 is base 8, or Octognal representation.
