Reverse Order Date String From File

[Cory]

This macro subroutine creates a reverse order date string from a file. The file name is passed from the parent to here where the date values are extracted and assembled into a reverse date order to be passed back to the parent. This is handy for file renames where you would like the files to keep the original file date and be in chronological order when sorted by name. I fond that the files are often moved to other machines causing it to loose the date stamp and also in some of my filing protocols we require the date first in YYYY-MM-DD format. However there are many uses for this.
