By default, in FORTRAN statement labels are placed on the same line, and backspaced from, the command that is being labeled, as in
EXIT: continue
This can look ugly if the label is very long. The command ‘-n:’ places the label on a separate line, as is done automatically for RATFOR—e.g.,
EXIT: continue
If neither of these options appeals to you, you could try redefining the
macro \Wlbl, found with some discussion in fwebmac.web.
That macro is emitted only when ‘-n:’ is not used.
