It just occurred to me today that DEC could make VMS friendlier by simply
generalizing their filespec for a list of files, i.e.:

	filespec1,filespec2,...	including wildcards, etc.

to include "@filespec", where filepec would be the spec of a file that has
a list of filespecs one to a line:

	@filespec, where filespec contains:

		filespec1, filespec2, filespec3   (or!)

		filespec1
		filespec2
		... (possibly even @filespec...)

this would really make certain types of operations easy, since there already
exist ways to create such "@filespec" files from various commmands under
VMS, such as	directory/nohead/notail/output=filespec matchfilespec..., or

		search/window=0/output=filespec matchfilespec...

then, if you were looking to make a list of files, for example, that
contain occurences of one match pattern and another, not necessarily on
the same line, you could just do:

		search/window=0/output=filespec searchfilelist pattern1

		search/window=0/output=finaloutput @filespec pattern2

etc., etc.... am I missing something, does vms already support this
functionality in some way (I don't mean this particular example, but the
general idea...)  Otherwise, you have to write several mindless dcl com
files to read such filelist files...  

	What an elegant extension this would be to VMS!  Yes?
