* open filename to filevar, keep opened files in named common
* 01-20-01 asb

This is good stuff. However, two things to keep in mind. The name of
the common block must be unique so that it doesn't inadvertently
collide with other programs. Named common stays alive your entire
login session so if you use the same name with different
configurations you could break
