Thank you for your summary. My analysis is that your :RECOG is just the
same thing as my :IF-EXISTS and :IF-DOES-NOT-EXIST except that I like my
names more, and a few minor details are different. I intentionally
omitted :IMAGE since I could not think of any definition that would be
portable and aid in the writing of portable programs. Certainly many
implementations will have their own :OPEN options.
You're quite right that we must specify which values of the defined
options are required for all implementations and which are optional. I
should probably have done this, but I'll leave it to GLS since he knows
more about the restrictions of the VAX, S-1, and Spice implementations
than I do.
