This is my first serious attempt at a writing a CMS assembler program.  I want
to be able to create to a file whose name is given as a parameter to the
program.  It seems that the FSCB macro requires that the filename be given in
quotes.  Since I won't know the filename at assembly time, how do I make this
generic?

My first idea is to code the macro with a dummy name and then insert the real
name into the proper location once I have gotten it.  Am I on the right track?
Anybody have code they are willing to share?

Thanks,
