Short: Open file requester in scripts. OS2.0 V1.3

FileRexx	Opens an ASL-filerequester on the frontmost PublicScreen, and
		prints the selected file/directory to StdOut, into an environ-
		ment-variable (if choosen), or into an arexx-variable (if File
		Rexx has opened a rexx-host).  The size of the filerequester
		will adjust automatically to the actual visible screensize if
		not affected from the given arguments.  Version 1.3, binary
		only.
