UNIQUE

var := UNIQUE dir ext mode digits [ offset ]

The STx command UNIQUE returns a unique filename for the specified directory (use "*" for the current working directory). If a directory is specified, it is made the current working directory first.

The unique filename will be returned without its path prefix and without an extension. If, for one reason or the other, STx should be unable to create a unique filename, it will return the empty string.

dir

The name of directory or "*" for the current working directory.

ext

The file extension.

mode

When supplying 0 for the mode argument, STx will generate the filename by using an internal decimal counter. When, on the other hand, supplying 1 for mode, STx will use a hexadecimal random number.

digits

The number of digits to use in the unique filename.

offset

The first index (for counter mode only).
