Well, I figured out how to make uasc files and use ms_$mapl:

     Use fopen to create the file, then fclose it. Now that the
     file already exists, you can map it without creating a nil
     type. Now, on to the next problem.

When I write files using ms_$mapl or C 'write' statements, the bytes
go exactly where I expect them to go. Only problem is, I have another
program in FORTRAN which uses the unformatted READ on the same files.
I constantly get the error:

      'data overflows buffer size'

I guess I either need end-of-record characters, or I need to change my
record length accordingly. Anyone have any experience with this? Anyone
know what character the end-of-record is, if there is one?

Thanks to anyone who can help,
Scott Ferguson
