Subject: [sftalk] Print Paging and Code Cleanup

Here is some kind of working code for printing a log file from within
a =
turnkey app. PRINT-LOG is attached to a menu item (DailyFile$ is set
=
elsewhere). =20

My problem: I have not been able to get paging to work (e.g., EOP
COUNT =
TYPE in ?PAGE does not do a page eject). Otherwise, it works ok but I
=
am sure that there must be a much simpler way to do this (this was a =
quick hack, be gentle). I had the expectation that the WINPRINT =
personality would patch up user variables such as PAGE, but I guess
not. =
 Also, I am maintaining a number of paging values that must have =
equivalents already defined.

Any suggestions on how to clean up my code and make the paging work?
It =
would also be nice to change fonts, do boldface, etc. Is there an
easy =
way to do this?
