Executable Names

Is there any way to tell the name of a program from inside of it? As in, if some retard renamed the program from its original name and you wanted to create a backup of the program from inside of itself, how would you tell the new name of the program?

Read the directory the app is in, find exe files, open them up for reading, search for a pre-defined tag (say a string... Class names are good'uns, but useless in Blitz, as you cannot predefine your own), if the string is in the file, erm, back up said file!

Another way is to check the size of the executable in the directory.

IIRC, one of the environment variables will contain the name of the running .EXE, and you can check those from within blitzplus.
